Answer:
x • (x2 - 2x - 5)
Explanation:
3.2 Factoring x2 - 2x - 5
The first term is, x2 its coefficient is 1 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 1 • -5 = -5
Step-2 : Find two factors of -5 whose sum equals the coefficient of the middle term, which is -2 .
-5 + 1 = -4
-1 + 5 = 4
So D
