Question 204560: X ^ 4 – 2 x ^ 2 = 8
That is: x to the fourth minus two x squared equals eight.
Find all solutions for x.
I have attempted this problem several times and am fighting with it, I thought to take the square root of both sides and that didn't work, and I tried adding eight to both sides but I am still stuck and don't know how to proceed. Please help! Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Solve for x: Subtract 8 from both sides of the equation. Now you can make this look like a quadratic equation by temporarily substituting Factor this. Apply the zero product rule. or which means that... or Re-substitute to get: or so this means that... or or or
