Homework Help: Math

Posted by Anonymous on Thursday, May 22, 2008 at 10:06pm.

How do you factor "0 = x^4 - 6x^2 + 5"? Please show all steps.


Here's my work, but I just went around in circles.....

0 = x^4 - 6x^2 + 5
-5 = x^4 - 6x^2
-5 = x^2 (x^2 - 6)
-5 / x^2 = x^2 - 6
(-5 / x^2) + 6 = x^2
(-5 + 6x^2) / (x^2) = x^2
-5 + 6x^2 = x^2 * x^2
-5 + 6x^2 = x^4
0 - x^4 - 6x^2 + 5
