15x/18x^2+(-12x)/18x^2-4+2=0

We add all the numbers together, and all the variables

15x/18x^2+(-12x)/18x^2-2=0

We multiply all the terms by the denominator


15x+(-12x)-2*18x^2=0

Wy multiply elements

-36x^2+15x+(-12x)=0

We get rid of parentheses

-36x^2+15x-12x=0

We add all the numbers together, and all the variables

-36x^2+3x=0

a = -36; b = 3; c = 0;
Δ = b2-4ac
Δ = 32-4·(-36)·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*-36}=\frac{-6}{-72}
=1/12
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+3}{2*-36}=\frac{0}{-72}
=0
