Exercise 41 Page 646

We will find and check the solutions of the given equation.

Finding the Solutions

To solve an equation with a variable expression inside a radical, we will first rearrange the radical equation so that the radical expression is isolated. Then, we can raise both sides of the equation to a power equal to the index of the radical. In this case, we will raise both sides of the equation to the second power. Let's do it! We now have a quadratic equation, and we need to find its roots. To do it, let's identify the values of $a,$ $b,$ and $c.$
