Question

Polynomial equation solution set??

Picture is attached below, I don't even know where to begin.. Thanks for the help!

Answer 1

Insert the given roots one by one in place of x. If they result in 0, this means that the solution set is true.

Answer 2

So if only one results in 0 its true?

Answer 3

No. All of them should result the same. i.e. 0.

Answer 4

Oh okay. I see what your saying. Thanks! I don't know why I didn't see that :P

Answer 5

Hmm. Me either.
