how many x intercepts appear on the graph of this polynomial function?

[lusty ruin]

f(x)=x^4-5x^2

The correct answer was three intercepts, but i chose two. Kinda really confused

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

In all honesty, I really need help in just finding x-intercepts of a polynomial without graphing

[brisk star]

divide each side by x^2

since f(x) = 0

0/ x^2 = 0

and just divide each term of the right

that should make it easier

ohh so (0,0) would also be considered an intercept?

[brisk star]

yes

[lusty ruin]

ohhh ok, thank you!!
