Zigmanuir [339]

Answer:

Zero

Step-by-step explanation:

To find the additive inverse, you merely change the sign of the number

For Example 5 {5 is the number} + (-5) {-5 is the additive inverse} = 0.

i.e. 6 + (-6) = 0

i.e (-7) + 7 = 0

The method in which you do this problem would be to FOIL. First Outer Inner Last. You take the first terms and multiply them. x*x = x^2 (x to the second power). Then you do it with the rest of foil.
x*x = x^2
x*1 = x
x*3 = 3x
1*3 = 3
x^2 + x + 3x + 3 = X^2 + 4x + 3
