axx+bx+c 2xx+7x+6
a=2
b=7
c=6
Multiply a and c:
2*6=12
Find multiples of ac that add up to b (d,e [ie de=ac, d+e=b]):
12=2*2*3
12=4*3, -4*-3
12=6*2, -6*-2
Rewrite axx+bx+c into axx+dx+ex+c:
2xx+7x+6
2xx+4x+3x+6
Factor sets of terms (ie axx+dx, and ex+c):
2xx+4x+3x+6
2x(x+2)+3(x+2)
Combine like terms:
2x(x+2)+3(x+2)
