(-32x^2)/72x^2+54x/72x^2+(-36x)/72x^2=0

We multiply all the terms by the denominator


(-32x^2)+54x+(-36x)=0

We get rid of parentheses

-32x^2+54x-36x=0

We add all the numbers together, and all the variables

-32x^2+18x=0

a = -32; b = 18; c = 0;
Δ = b2-4ac
Δ = 182-4·(-32)·0
Δ = 324
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{324}=18$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(18)-18}{2*-32}=\frac{-36}{-64}
=9/16
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(18)+18}{2*-32}=\frac{0}{-64}
=0
