108y^2+15y+(-6y)=0

We get rid of parentheses

108y^2+15y-6y=0

We add all the numbers together, and all the variables

108y^2+9y=0

a = 108; b = 9; c = 0;
Δ = b2-4ac
Δ = 92-4·108·0
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*108}=\frac{-18}{216}
=-1/12
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+9}{2*108}=\frac{0}{216}
=0
