44x/8x^2+(-2x)/8x^2-4-6=0

We add all the numbers together, and all the variables

44x/8x^2+(-2x)/8x^2-10=0

We multiply all the terms by the denominator


44x+(-2x)-10*8x^2=0

Wy multiply elements

-80x^2+44x+(-2x)=0

We get rid of parentheses

-80x^2+44x-2x=0

We add all the numbers together, and all the variables

-80x^2+42x=0

a = -80; b = 42; c = 0;
Δ = b2-4ac
Δ = 422-4·(-80)·0
Δ = 1764
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1764}=42$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(42)-42}{2*-80}=\frac{-84}{-160}
=21/40
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(42)+42}{2*-80}=\frac{0}{-160}
=0
