We calculate fractions


(-8x)/16x^2+(-6x)/16x^2-1=0

We multiply all the terms by the denominator


(-8x)+(-6x)-1*16x^2=0

Wy multiply elements

-16x^2+(-8x)+(-6x)=0

We get rid of parentheses

-16x^2-8x-6x=0

We add all the numbers together, and all the variables

-16x^2-14x=0

a = -16; b = -14; c = 0;
Δ = b2-4ac
Δ = -142-4·(-16)·0
Δ = 196
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{196}=14$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-14)-14}{2*-16}=\frac{0}{-32}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-14)+14}{2*-16}=\frac{28}{-32}
=-7/8
