We get rid of parentheses

-1/2x-5/8x-2=0

We calculate fractions


(-8x)/16x^2+(-10x)/16x^2-2=0

We multiply all the terms by the denominator


(-8x)+(-10x)-2*16x^2=0

Wy multiply elements

-32x^2+(-8x)+(-10x)=0

We get rid of parentheses

-32x^2-8x-10x=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{0}{-64}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+18}{2*-32}=\frac{36}{-64}
=-9/16
