36x^2=324

Solution for 36x^2=324 equation:

36x^2=324

We move all terms to the left:

36x^2-(324)=0

a = 36; b = 0; c = -324;
Δ = b2-4ac
Δ = 02-4·36·(-324)
Δ = 46656
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{46656}=216$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-216}{2*36}=\frac{-216}{72}
=-3
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+216}{2*36}=\frac{216}{72}
=3
