Question

Factor out the GCF from the expression.
48x^5-16x^3= 16&48 have a GCF of 16
-16(x^3-3x^5)
Can someone tell me if this is correct?

Answer 1

your on the right track but look at your variable x. Can you do any thing with it?

Answer 2

add the exponents? ( sry my comp froze)

Answer 3

GCF you said was 16 that was for the numbers but you have a GCF for the variable x as well.... so what do you think that might be?

Answer 4

x^1 ?

Answer 5

no it x^3 because there are x to the third power in each component.

Answer 6

oh, ok

Answer 7

so then the answer would be, 48x^5-16x^3=16x^3(3x^2-1) ?

Answer 8

yes
