We get rid of parentheses

8/2x-6/x-87+12=0

We calculate fractions


8x/2x^2+(-12x)/2x^2-87+12=0

We add all the numbers together, and all the variables

8x/2x^2+(-12x)/2x^2-75=0

We multiply all the terms by the denominator


8x+(-12x)-75*2x^2=0

Wy multiply elements

-150x^2+8x+(-12x)=0

We get rid of parentheses

-150x^2+8x-12x=0

We add all the numbers together, and all the variables

-150x^2-4x=0

a = -150; b = -4; c = 0;
Δ = b2-4ac
Δ = -42-4·(-150)·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-4)-4}{2*-150}=\frac{0}{-300}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4)+4}{2*-150}=\frac{8}{-300}
=-2/75
