Solving Quadratic Equations with Square Roots

To solve the given equation by taking square roots, we need to start by isolating

x^{2}

on one side of the equation.

- x^{2} + 9 = 9

LHS - 9 = RHS - 9

- x^{2} = 0

LHS / (- 1) = RHS / (- 1)

x^{2} = 0

CalcRootCalculate root

x = 0

We found that

x = 0 .

Therefore, there is only one solution for the equation:

x = 0 .
