We calculate fractions


6x/48x^2+8x/48x^2-1=0

We multiply all the terms by the denominator


6x+8x-1*48x^2=0

We add all the numbers together, and all the variables

14x-1*48x^2=0

Wy multiply elements

-48x^2+14x=0

a = -48; b = 14; c = 0;
Δ = b2-4ac
Δ = 142-4·(-48)·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*-48}=\frac{-28}{-96}
=7/24
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(14)+14}{2*-48}=\frac{0}{-96}
=0
