(-108a^2)/288a^2+96a/288a^2+(-240a)/288a^2=0

We multiply all the terms by the denominator


(-108a^2)+96a+(-240a)=0

We get rid of parentheses

-108a^2+96a-240a=0

We add all the numbers together, and all the variables

-108a^2-144a=0

a = -108; b = -144; c = 0;
Δ = b2-4ac
Δ = -1442-4·(-108)·0
Δ = 20736
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{20736}=144$
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-144)-144}{2*-108}=\frac{0}{-216}
=0
$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-144)+144}{2*-108}=\frac{288}{-216}
=-1+1/3
