Question

Find the product.
(6a + 3b)(a - b)
Enter the correct answer.

Answer 1

6a^2-3b^2-6ba+3ba

Explanation:

(6a+3b)(a+b)....expand the term

6axa - 6axb + 3bxa - 3b×b ....simplify

6a^2 - 6ba + 3ba - 3b^2, then reorder so highest order terms come first

6a^2 - 3b^2 - 6ba + 3ba

Answer 2

See below.

Explanation:

`(6a+3b)(a-b)\\`

Distribute:

`=(6a+3b)(a)-(6a+3b)(b)\\=6a^2+3ab-(6ab+3b^2)\\=6a^2+3ab-6ab-3b^2\\=6a^2-3b^2-3ab`
