What are the zeros in f(x)=x^5+x^3-6x?

Answer 1

what do we get when we factor a GCF?

Answer 2

Isn't the GCF 1?

Answer 3

i was going for x

Answer 4

f(x) = x(x^4 + x^2 -6)

so we know x=0 makes this equal to 0

now to work the hidden quadratic, let a = x^2 such that

a^2 + a - 6 = 0

Answer 5

So x(x^4+x^2-6)?

Answer 6

yep

Answer 7

Oh ok I got it now, thank you!

Answer 8

youre welcome, good luck :)
