(-180x^2)+1296x^2+324x+(-288x)=0

We get rid of parentheses

-180x^2+1296x^2+324x-288x=0

We add all the numbers together, and all the variables

1116x^2+36x=0

a = 1116; b = 36; c = 0;
Δ = b2-4ac
Δ = 362-4·1116·0
Δ = 1296
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1296}=36$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(36)-36}{2*1116}=\frac{-72}{2232}
=-1/31
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(36)+36}{2*1116}=\frac{0}{2232}
=0
