Question

25 Points. Subtract the Polynomials. Please help I need to get this whole test done asap. If you would be able to help me with the whole thing such as giving me instructions on what to do that would be much appreciated.

Answer 1

Hello from MrBillDoesMath!

Answer:

8ab + 9a -6

Discussion:

(3ab + 9a -2) - ( -5ab + 4)  =          => as -(-5ab) = +5ab and -(4) = -4

(3ab + 9a - 2) + 5ab -4       =          => combine like terms

(3ab + 5ab) + 9a -2 -4         =         => as 3ab + 5ab = 8 ab

8ab + 9a -6

Thank you,

MrB
