We calculate fractions


6y/12y^2+(-2y)/12y^2+1=0

We multiply all the terms by the denominator


6y+(-2y)+1*12y^2=0

Wy multiply elements

12y^2+6y+(-2y)=0

We get rid of parentheses

12y^2+6y-2y=0

We add all the numbers together, and all the variables

12y^2+4y=0

a = 12; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·12·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4}{2*12}=\frac{-8}{24}
=-1/3
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*12}=\frac{0}{24}
=0
