Question

Which of the following represents the factored form of f(x) = x^3 − 64x?
f(x) = x(x + 8)(x − 8)
f(x) = (x − 8)(x + 8)
f(x) = x(x − 8)^2
f(x) = x(x^2 − 8)

Answer 18

o ok :/

Answer 19

@Nnesha can you help?

Answer 20

first find GCF(greatest common factor )
so there is x common in both terms right ?
now take out the x from x^3 and -64x
or in other words divide both terms by common factor
\[\rm x^3-64x=x(???-???)\]

Answer 21

divide both terms by common factor and write your answer in the parentheses.
