I need to find the X-intercepts of:

Y= 3x^4 - 6x^2 + 5/3

Thank you for any help.

I have been away from any math for over five years so a step by step would be appreciated.

I really don't even know what to do from there. Sorry for being a pain. I really should have relearned some of these skills before signing up for calc class.:(

When I used the quadratic equation I got:

k= 3 and,

k= .6

When I replaced k with X^2 I get

X= +/- sqrt(3)

X= +/- sqrt(.6)

These answers don't match up with the intercepts when I check them on the graphing calc. - Nov 26th 2007, 07:23 PMJhevon
