a To solve equations with a variable expression inside a square root, we first want to make sure the radical is isolated. Then we can raise both sides of the equation to a power equal to the index of the radical. Let's try to solve our equation using this method!
We found that the solutions to the equation are 1 and 4.
Finally, we will check our solutions by substituting the value into the original equation. Let's start with x=1.
This time we created a true statement. Therefore, x=4 is indeed a solution to the given equation.
b To solve equations with a variable expression inside a square root, we first want to make sure the radical is isolated. Then we can raise both sides of the equation to a power equal to the index of the radical. Note that the square root is already isolated. Let's solve the equation!
