Can i have . find the difference 3 - (-5u^2 + 9) a. 5u^2 + 12 b. 8u^2 + 12 c. -5u^2 + 12 d. 5u^2 - 6 e. 8u^2 - 6

5 u^2 + -6 thus the answer is D.

Step-by-step explanation:

Simplify the following:

-(-5 u^2 + 9) + 3

Factor -1 out of 9 - 5 u^2:

3 - -(5 u^2 - 9)

(-1)^2 = 1:

5 u^2 - 9 + 3

Grouping like terms, 5 u^2 - 9 + 3 = 5 u^2 + (3 - 9):

5 u^2 + (3 - 9)

3 - 9 = -6:

 5 u^2 + -6

do i do it on a graph?
