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.
use the quadratic formula.
for a quadratic of the form $\displaystyle y = ax^2 + bx + c$ the roots (that is, the solution(s) to $\displaystyle ax^2 + bx + c = 0$) are given by:
$\displaystyle x = \frac {-b \pm \sqrt{b^2 - 4ac}}{2a}$
use that to solve for k. when done, replace k with x^2 and solve for x
