112=y^2-y

Solution for 112=y^2-y equation:

112=y^2-y

We move all terms to the left:

112-(y^2-y)=0

We get rid of parentheses

-y^2+y+112=0

We add all the numbers together, and all the variables

-1y^2+y+112=0

a = -1; b = 1; c = +112;
Δ = b2-4ac
Δ = 12-4·(-1)·112
Δ = 449
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-\sqrt{449}}{2*-1}=\frac{-1-\sqrt{449}}{-2}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{449}}{2*-1}=\frac{-1+\sqrt{449}}{-2}
