(-36x^2)/96x^2+48x/96x^2+(-64x)/96x^2=0

We multiply all the terms by the denominator


(-36x^2)+48x+(-64x)=0

We get rid of parentheses

-36x^2+48x-64x=0

We add all the numbers together, and all the variables

-36x^2-16x=0

a = -36; b = -16; c = 0;
Δ = b2-4ac
Δ = -162-4·(-36)·0
Δ = 256
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{256}=16$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-16)-16}{2*-36}=\frac{0}{-72}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-16)+16}{2*-36}=\frac{32}{-72}
=-4/9
