Need Help with :
finding real solutions.
x4-3x2+2=0
the numbers after the x's are the powers.
also if i need to type in square roots how do i do that?
First, new questions should be placed in new threads.
BUT
I already answered this in your other thread. If you cannot understand my solution that thread is the one you should make a mention of it. That's only polite.
AND
Please don't double post. See rule #1 here.
