If the coefficient of the a-term is not 1, divide every
term on BOTH sides of the equation by it.
1.
Isolate the a- and b-terms (bring the constant to the
other side).
2.
Divide b-term by 2 and square it. (Think: box
method!)
3.
a.
Add it to both sides
b.
Simplify the right side of the equation
Factor the left side of the equation.
4.
5.
Isolate y.
