Question

Which is a factor of x2 + 5x – 24?

A.) (х – 6)
B.) (х + 6)
C.) (х – 8)
D.) (х + 8)

Answer 1

Good evening ,

Answer:

D. (х + 8)

Explanation:

Since 8² + 5(-8) - 24 = 64 - 40 - 24 = 0 then 8 is a root of x² + 5x – 24

then (x-(-8)) is a factor of x² + 5x – 24

then (x+8) is a factor of x² + 5x – 24.
