Equation at the end of step 1 : ((8 • (a2)) - 2ab) - (3•7b2)
Step 2 :Equation at the end of step 2 : (23a2 - 2ab) - (3•7b2)
Step 3 :Trying to factor a multi variable polynomial :
3.1 Factoring 8a2 - 2ab - 21b2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (4a - 7b)•(2a + 3b)
Final result : (4a - 7b) • (2a + 3b)
