We multiply all the terms by the denominator


(-16x^2)+54x+(-36x)-5*72x^2=0

Wy multiply elements

(-16x^2)-360x^2+54x+(-36x)=0

We get rid of parentheses

-16x^2-360x^2+54x-36x=0

We add all the numbers together, and all the variables

-376x^2+18x=0

a = -376; b = 18; c = 0;
Δ = b2-4ac
Δ = 182-4·(-376)·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*-376}=\frac{-36}{-752}
=9/188
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(18)+18}{2*-376}=\frac{0}{-752}
=0
