Question

What are the real or imaginary solutions of the polynomial equation?

x4 – 52x2 + 576 = 0

Answer 1

Nice wolfram

Answer 2

yea

Answer 3

Look for two numbers a and b, with a+b=-52 and ab=576.
These numbers are -36 and -16.
So:\[x^4-52x^2+576=(x^2-36)(x^2-16)\]Now, look up @stgreen 's solution, then you'll see you can factor this even more! All 4 solutions are real...

Answer 4

Look ma, no Wolfram!

Answer 5

good

Answer 6

I don't blame him. Kids here want answers to all their quizzes/homework and they don't even know about wolfram. I don't think they should though.

Answer 7

and now you're are tempting 'em google it

Answer 8

Well, they found this by googling yet they couldn't find the wolf. Sigh.

Answer 9

Man, I use mathematica lol.

Answer 10

its just i don't wanna spend time on such questions so i go for it to help kids

Answer 11

mmm
