8x/12x^2+6x/12x^2-10=0

We multiply all the terms by the denominator


8x+6x-10*12x^2=0

We add all the numbers together, and all the variables

14x-10*12x^2=0

Wy multiply elements

-120x^2+14x=0

a = -120; b = 14; c = 0;
Δ = b2-4ac
Δ = 142-4·(-120)·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*-120}=\frac{-28}{-240}
=7/60
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(14)+14}{2*-120}=\frac{0}{-240}
=0
