Solving Square Roots

What is the first step to solving a square root equation?

• Isolate the radical

• Square both sides

• Solve Algebraically

• Plug in the solution to the equation

What is the parent function of square root functions?

• f(x) = x

• f(x) = √x

• f(x) = x²

After isolating the radical, what is the next step?

• Square both sides

• divide

• plug in the solution

• isolate the variable

What is the first step to solve this equation?

• Add 6 to both sides

• Square both sides

• Square root both sides
