We calculate fractions


(-48x^2)/48x^2+16x/48x^2+(-12x)/48x^2-1=0

We multiply all the terms by the denominator


(-48x^2)+16x+(-12x)-1*48x^2=0

Wy multiply elements

(-48x^2)-48x^2+16x+(-12x)=0

We get rid of parentheses

-48x^2-48x^2+16x-12x=0

We add all the numbers together, and all the variables

-96x^2+4x=0

a = -96; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·(-96)·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*-96}=\frac{-8}{-192}
=1/24
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*-96}=\frac{0}{-192}
=0
