Question

Factor out the greatest common factor in the expression
x^2(x-4) + 15(x-4)

Answer 1

Each term is a product (meaning, multiplication) of 2 FACTORS.

In the first, you multiply \(x^2\) and (x-4).
In the second, you multiply 15 and (x-4)

So all of the factors, in both terms are:
x (2 factors in the first term)
(x-4) (a binomial factor, in both terms)
and
15 (which really breaks down to a factor of 3, and a factor of 5, in the second term)

So you tell me, what is the GCF?

Answer 2

take x-4 common

Answer 3

Yes, that is the GCF. :)

Answer 4

i put the answer like this (x-4) nd like this x-4 they said its incorrect
