We calculate fractions


12y/18y^2+(-3y)/18y^2+2=0

We multiply all the terms by the denominator


12y+(-3y)+2*18y^2=0

Wy multiply elements

36y^2+12y+(-3y)=0

We get rid of parentheses

36y^2+12y-3y=0

We add all the numbers together, and all the variables

36y^2+9y=0

a = 36; b = 9; c = 0;
Δ = b2-4ac
Δ = 92-4·36·0
Δ = 81
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{81}=9$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-9}{2*36}=\frac{-18}{72}
=-1/4
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+9}{2*36}=\frac{0}{72}
=0
