Question

HEEELP!! Expand and simplify.
(3m + 2)(m - 3) - (2m - 1)(m + 3)
Answer: m^2 - 12m - 3

Answer 1

To multiply two binomials together, you multiply both terms of the first binomial by both terms of the second binomial.
(3m + 2)(m - 3) - (2m - 1)(m + 3) =
(3m)(m) + (3m)(-3) + (2)(m) + (2)(-3) - [(2m)(m) + (2m)(3) + (-1)(m) + (-1)(3)]

Answer 2

Alright, I'll try that. Thank you (:
