10y/20y^2+(-2y)/20y^2+6=0

We multiply all the terms by the denominator


10y+(-2y)+6*20y^2=0

Wy multiply elements

120y^2+10y+(-2y)=0

We get rid of parentheses

120y^2+10y-2y=0

We add all the numbers together, and all the variables

120y^2+8y=0

a = 120; b = 8; c = 0;
Δ = b2-4ac
Δ = 82-4·120·0
Δ = 64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{64}=8$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(8)-8}{2*120}=\frac{-16}{240}
=-1/15
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(8)+8}{2*120}=\frac{0}{240}
=0
