Question

A. f(x) = x2 – 11x – 12

Answer 1

Answer:

Order is B, D, A, C

Step-by-step explanation:

A.$f(x) = x^2 - 11x - 12$

Product is -12 and sum is -11. factors are -12 and 1

$f(x) = (x - 12)(x + 1)$

B.$f(x) = x^2 - 4x - 12$

Product is -12 and sum is -4. factors are -6 and 2

$f(x) = (x - 6)(x +2)$

C.$f(x) = x^2 +x - 12$

Product is -12 and sum is +1. factors are +4 and -3

$f(x) = (x +4)(x -3)$

D.$f(x) = x^2 -x - 12$

Product is -12 and sum is -1. factors are -4 and +3

$f(x) = (x -4)(x +3)$

Answer 2

A
$(x - 12)(x + 1)$
B
$(x + 2)(x - 6)$
