Simplify (9a)(5ab) - (3a2)(9b).

62% Answer Correctly
72a2b
18a2b
72ab2
168ab2
Solution

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

(9a)(5ab) - (3a2)(9b)
(9 x 5)(a x a x b) - (3 x 9)(a2 x b)
(45)(a1+1 x b) - (27)(a2b)
45a2b - 27a2b
18a2b
