We get rid of parentheses

3/4x-1/2x-3-1/2=0

We calculate fractions


24x/32x^2+(-4x)/32x^2+(-4x)/32x^2-3=0

We multiply all the terms by the denominator


24x+(-4x)+(-4x)-3*32x^2=0

Wy multiply elements

-96x^2+24x+(-4x)+(-4x)=0

We get rid of parentheses

-96x^2+24x-4x-4x=0

We add all the numbers together, and all the variables

-96x^2+16x=0

a = -96; b = 16; c = 0;
Δ = b2-4ac
Δ = 162-4·(-96)·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*-96}=\frac{-32}{-192}
=1/6
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(16)+16}{2*-96}=\frac{0}{-192}
=0
