Answer:
5 x^2 - 32
Step-by-step explanation:
Simplify the following:
3 x^2 + 2 x^2 - 32
Grouping like terms, 3 x^2 + 2 x^2 - 32 = (2 x^2 + 3 x^2) - 32:
(2 x^2 + 3 x^2) - 32
2 x^2 + 3 x^2 = 5 x^2:
Answer: 5 x^2 - 32

Answer:
Step-by-step explanation:
<u>Let's factor the trinomial:</u>
- x² + 14x + 40 =
- x² + 4x + 10x + 40 =
- x(x + 4) + 10(x + 4) =
- (x + 4)(x + 10)
x + 4 is between the answer options
Correct option is D.
