Question

Which of the following represents the factored form of f(x) = x3 − 81x?

f(x) = x(x − 9)2
f(x) = (x + 9)(x − 9)
f(x) = x(x + 9)(x − 9)
f(x) = x(x2 − 9)

Answer 7

Sorry lost internet connection. First you need to factor out an x
=(x)(x^2-81)
Now you simplify x^2-81
=(x)(x+9)(x-9)

Answer 8

B is just x^2-81, so it can't be B

Answer 9

it can't be d either so the answer has to beee
