(-16x^2)/72x^2+18x/72x^2+(-36x)/72x^2-2=0

We multiply all the terms by the denominator


(-16x^2)+18x+(-36x)-2*72x^2=0

Wy multiply elements

(-16x^2)-144x^2+18x+(-36x)=0

We get rid of parentheses

-16x^2-144x^2+18x-36x=0

We add all the numbers together, and all the variables

-160x^2-18x=0

a = -160; b = -18; c = 0;
Δ = b2-4ac
Δ = -182-4·(-160)·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*-160}=\frac{0}{-320}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+18}{2*-160}=\frac{36}{-320}
=-9/80
