Simplify.

7 (3u+8) (u + 3)

35 (u-6) (3u+8)

You may leave the numerator and denominator of your answer in factored form.

1.) 21u² + 119u + 168

2.) 105u² - 350u - 1680

Step-by-step explanation:

1.) 7 (3u+8) Distribute the 7 into the parentheses.

(21u + 56) (u + 3) Multiply the parentheses.

21u² + 119u + 168

2.) 35 (u - 6) Distribute the 35 into the parentheses.

(35u - 210) (3u + 8) Multiply the parentheses.

105u² + 280u - 630u - 1680 Combine like terms.

105u² - 350u - 1680
