Question

A quadratic function is defined by ƒ (x) = x² + 5x − 24.

Which of the following expresses ƒ (x) as the product of
two linear factors?
A
B
C
ƒ (x) = (x − 4) (x + 6)
f(x) = (x − 3)(x + 8)
f(x) = (x + 3) (x − 8)
D fl
f(x) = (x + 4) (x - 6)

Answer 1

Factors of -24 are 8 and -3/ -8 and 3. You choose the 8 and -3 because 8+-3=5
