The answer is C.
Point G can be centroid because 12:6 equals 2:1
FG = 6
FC = 18
so
GC = 12
12:6 = 2:1
Answer:
c. (x +3)(x + 1)
Step-by-step explanation:
Factoring an equation is a way of expressing an equation as the product of other linear expressions. The following expression,

Can be represented as the product of the following,

To check this, one can distribute, one of the expressions over the other, then simplify, the result should be the starting expression,

Distribute,

Simplify,


X cannot equal +2, and can't be -1. If you factor it, then you notice you get 2(x+2)(x-2). If you use either one for the x, one will be zero and the won't, and vise-versa.
