2xx-56x+180

2(xx-28+90)

axx+bx+c

a=1

b=-28

c=90

Multiply a and c:

1*90=90

Find multiples of ac that add up to b (d,e [ie de=ac, d+e=b]):

90=2*3*3*5

2*45

3*30

5*18

6*15

9*10

NONE add up to -28, use quadratic

Rewrite axx+bx+c into axx+dx+ex+c:

Factor sets of terms (ie axx+dx, and ex+c):
