We multiply all the terms by the denominator


(-12x^2)+144x+(-108x)-15*216x^2=0

Wy multiply elements

(-12x^2)-3240x^2+144x+(-108x)=0

We get rid of parentheses

-12x^2-3240x^2+144x-108x=0

We add all the numbers together, and all the variables

-3252x^2+36x=0

a = -3252; b = 36; c = 0;
Δ = b2-4ac
Δ = 362-4·(-3252)·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*-3252}=\frac{-72}{-6504}
=3/271
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(36)+36}{2*-3252}=\frac{0}{-6504}
=0
