Take the square root of both sides of the equation.
$$x=0$$ $$x=0$$
The equation is now solved. Solutions are the same.
$$x=0$$
Steps Using the Quadratic Formula
Divide $36$ by $2$ to get $18$.
$$x^{2}+18=18$$
Subtract $18$ from both sides.
$$x^{2}+18-18=0$$
Subtract $18$ from $18$ to get $0$.
$$x^{2}=0$$
This equation is in standard form: $ax^{2}+bx+c=0$. Substitute $1$ for $a$, $0$ for $b$, and $0$ for $c$ in the quadratic formula, $\frac{-b±\sqrt{b^{2}-4ac}}{2a}$.
