x∈R


We calculate fractions


5x/2x^2+(-2x)/2x^2-6=0

We multiply all the terms by the denominator


5x+(-2x)-6*2x^2=0

Wy multiply elements

-12x^2+5x+(-2x)=0

We get rid of parentheses

-12x^2+5x-2x=0

We add all the numbers together, and all the variables

-12x^2+3x=0

a = -12; b = 3; c = 0;
Δ = b2-4ac
Δ = 32-4·(-12)·0
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-3}{2*-12}=\frac{-6}{-24}
=1/4
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+3}{2*-12}=\frac{0}{-24}
=0
