Question

Simplify the following expression.

Answer 1

Answer: A. -10u³ - 16u² + 4u

Answer 2

Answer: $-10u^{3}-16u^{2}+4u$

Step-by-step explanation:

To solve the problem shown in the image attached, you must apply a property called  Distributive property of multiplication. This means that you must multiply each term inside the parentheses by $2u$.

Therefore, keeping this on mind, you obtain the following result:

$2u(-5u^{2}-8u+2)=(2u)(-5u^{2})+(2u)(-8u)+(2u)(2)= -10u^{3}-16u^{2}+4u$
