9. Consider the function f(x) = x² + 3x – 4.

BaLLatris [955]

Answer:

c. f(x) = (x + 4)(x - 1)

Step-by-step explanation:

Since you're familiar with the product of two binomials:

(x +a)(x +b) = x² + (a+b)x + ab

you know that the constants in the binomial factors must ...

have a product of -4
have a sum of +3

All of the choices except B have binomial constants that have a product of -4.

In order, the sums of the remaining choices are ...

A: 1-4 = -3

C: 4-1 = 3 . . . . this is the correct choice

D: -2+2 = 0
