The answer is (x+1)²= x²+2x+1
so x^2 + 2x must be added 1 to become  x²+2x+1=<span>(x+1)²</span>

URGENT! find the sum. the answer is not D​

<h3>Answer:  C)  -1/2</h3>

=============================================

Explanation:

We'll apply the derivative to get

g(x) = 4x^3 + 3x^2

g ' (x) = 3*4x^2 + 2*3x

g ' (x) = 12x^2 + 6x

Set that equal to 0 and solve for x. We do this to find where the horizontal tangents are located.

g ' (x) = 0

12x^2 + 6x = 0

6x(2x + 1) = 0

6x = 0 or 2x+1 = 0

x = 0 or x = -1/2

Adding those two said solutions yields us the final answer choice C
