Answer:
D is the answer
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
((0 - 5x2) - 8x) - 11 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-5x2 - 8x - 11 = -1 • (5x2 + 8x + 11)
Trying to factor by splitting the middle term
3.2 Factoring 5x2 + 8x + 11
The first term is, 5x2 its coefficient is 5 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is +11
Step-1 : Multiply the coefficient of the first term by the constant 5 • 11 = 55
Step-2 : Find two factors of 55 whose sum equals the coefficient of the middle term, which is 8 .
