Which is true about the completely simplified difference of the polynomials a3b + 9a2b2 − 4ab5 and a3b − 3a2b2 + ab5?

1 answer

The completely simplified difference of the polynomials a3b + 9a2b2 − 4ab5 and a3b − 3a2b2 + ab5 is:

(9a2b2 - 3a2b2) = 6a2b2

(-4ab5 - ab5) = -5ab5

Therefore, the difference of the two polynomials is 6a2b2 - 5ab5.
