Question

is 2x^3 the gcf of 30x^3+6x^5

Answer 1

the x^3 is correct, but not the 2

Answer 2

why not?

Answer 3

because a larger number goes into both 6 and 30

Answer 4

2 is a factor of both, but not the GCF

Answer 5

oh the options I have are 16x, 2x^3, 2x^5, x^3

Answer 6

well that's just stupid...the GCF is really 6x^3 since 6 is the GCF of 6 and 30

Answer 7

2x^3 is a factor, but not the GCF

Answer 8

oh wait I typed the ques in wrong, its 16 not 6.im so sorry

Answer 9

\[30x^{3} + 16x^{5} = 2(15x^{3} + 8x^{5}) = 2x^{3}(15 + 4x^{2})\]

Answer 10

So the GCF is 2x^3

Answer 11

Oops, 4x^2 should be 8x^2

Answer 12

so if the expression is really 16x^3+6x^5

then yes, the GCF is 2x^3

16x^3+6x^5 = 2x^3 ( 8 + 3x^2 )

Answer 13

ok thanks a lot :)
