Radical Equations And Problem Solving

Even the best athletes and musicians had help along the way and lots of practice, practice, practice, to get good at their sport or instrument. If you need a review on radicals in general, feel free to go to. For example, if the rational exponent is 23, then the inverse operation is to raise both sides to the 32 power.

If the left side does not equal the right side, then you have an extraneous solution. For solving over the real (general solutions), you can put the period of the trig function and then add the appropriate factors of remember for the reciprocal functions, take the reciprocal of whats on the right hand side, and use the regular trig functions. These are practice problems to help bring you to the next level.

If that is the case and you have at least one nonradical term, you will probably have to repeat steps 1 and 2. If you need a review on squaring a binomial, feel free to go to   it is very tempting to square the left side term by term and get  squared plus 1. Im using fancy notation you may not be required to do this.

You can also type in your own problem, or click on the three dots in the upper right hand corner and click on examples to drill down by topic. If a value is an extraneous solution, it is not a solution to the original problem. .

Once we get the initial solution(s), well need to plug in to get the other variable. However, there are some problems that have more than one radical. In this tutorial, we will be looking at solving two different types of equations, radical equations and equations that have rational exponents.

If you need a review on rational exponents in general, feel free to go to. However, you need to square it as a side as shown above. This will sometimes happen if trig functions are squared in the problems also, since well getting plusses and minuses. When solving equations with rational exponents, extra solutions may come up when you raise both sides to an even power. A free math site with a practical approach and happens to include more girls examples.

    I think you are ready to tackle these equations. If you need a review on solving quadratic equations, feel free to go to when solving radical equations, extra solutions may come up when you raise both sides to an even power. You can raise both sides to the 2nd power, 10th power, hundredth power, etc. Unit circle to see where the solutions are in the we still use the unit circle to do this, but we have to think about adding and subtracting multiples of radians apart, so one set of solutions will the same as the other, and we can collapse into one solution and add. However, there are some problems that have more than one radical.

    The inverse operation to a radical or a root is to raise it to an exponent. Lets do some problems, finding the general solutions first, and then finding the solutions in the 0 to 2 note that when we multiply or divide to get the variable by itself, we have to do the same with the 2 now lets solve the same multiple angle problems, but get solutions between 0 and 2 note again that when we solve these types of trig problems, we always want to first, and then go back and see how many solutions are on the unit circle (between 0 and 2. Then we set all factors to 0 to solve, making sure we test the answers to see if they work. Once we get the initial solution(s), well need to plug in to get the other variable. For solving over the real (general solutions), you can put the period of the trig function and then add the appropriate factors of remember for the reciprocal functions, take the reciprocal of whats on the right hand side, and use the regular trig functions.

    If you need a review on squaring a binomial, feel free to go to in other words get the base with the rational exponent on one side and everything else on the other using inverse operations. As long as you do the same thing to both sides of the equation, the two sides will remain equal to each other. In this tutorial, we will be looking at solving two different types of equations, radical equations and equations that have rational exponents. If the left side does not equal the right side than you have an extraneous solution. It will allow you to check and see if you have an understanding of these types of problems. In other words, get one radical on one side and everything else on the other using inverse operations. This will sometimes happen if trig functions are squared in the problems also, since well getting plusses and minuses. But if we are solving (displaystyle sin left( x right)fracsqrt22) we get (displaystyle fracpi 4) and (displaystyle frac3pi 4)  in the interval (left( 0,2pi right)) there are no lets start out with solving fairly simple trig equations and getting the solutions from  (left 0,,,2pi right)), or (left 0,360o right). For tan, cot, csc, and sec, we have asymptotes, and if our answer happens to fall on an asymptote, we have to eliminate it. Also, after removing the radical or rational exponent in the equations in this tutorial, they become either a linear or quadratic equation.

    Practice some problems before going into the exercise.

In equations with rational exponents you check for extraneous solutions by plugging in the values you found back into the original problem. In other words, if you had a square root, you would have to square it to get rid of it. You can raise both sides to the 2nd power, 10th power, hundredth power, etc.

    If you need a review on squaring a binomial, feel free to go to   it is very tempting to square the left side term by term and get  squared plus 1. If you raise an expression that has a rational exponent to the reciprocal of that rational exponent, the exponent will disappear. So, we do not have to do anything on this step for this example. Once we get the initial solution(s), well need to plug in to get the other variable. The inverse operation to a radical or a root is to raise it to an exponent.
