Equation at the end of step 1 : (((4•(a2))•b)-((8•(a3))•(b5)))+2ab7Equation at the end of step 2 : (((4•(a2))•b)-(23a3•b5))+2ab7
Step 3 :Equation at the end of step 3 : ((22a2 • b) - 23a3b5) + 2ab7
Step 4 :Step 5 :Pulling out like terms :
5.1 Pull out like factors :
-8a3b5 + 4a2b + 2ab7 = -2ab • (4a2b4 - 2a - b6)
