Answer 1

Answer:

$-11u^{2} -9u-4$

Step-by-step explanation:

$-11u^{2}-7u-7-2u+3$

$-11u^{2} -9u-7+3$

$-11u^{2} -9u-4$

Answer 2

Answer:

$- 11 {u}^{2} - 9u - 4$

Step-by-step explanation:

1) Collect like terms.

$( {4u}^{2} - {15u}^{2} ) + ( - 7u - 2u) + ( - 7 + 3)$

2) Simplify.

$( { - 11u}^{2} - 9u - 4)$

Therefor, the answer is ( - 11u² - 9u - 4).
