Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 2 and 3 x2 + 2x + 3x + 6
Step-4 : Add up the first 2 terms, pulling out like factors : x • (x+2) Add up the last 2 terms, pulling out common factors : 3 • (x+2) Step-5 : Add up the four terms of step (x+3) (x+2)
