It's simplified unless you're looking for imaginary roots

in the term 3x^2+2x+1, you would need to multiply the x to the first degree by 3x at least once, which doesn't appear to have happened seeing how the x to the first degree has a coefficent of 2

don't worry, you probably don't need to find imaginary roots unless told to do so.

I believe the answer is 3x^2+4x+2 by combining like terms. However, I may be wrong.

the two terms are being multiplied, not added, h3rpd3rp, so that would be incorrect

Maybe it wants you to multiply it out

oh right. *face palm* Would you still be able to do like terms though? Just multiplying them instead?

That seems a bit cruel, though. However, the answer would be 6x^3 + 7x^2 + 4x + 1

I don't think your teacher wants you to expand the polynomial nor for you to find imaginary roots. My best guess is that the answer is 'simplified'

is this the right answer? 16x^4 + 4x^2 +2

for this, you would have to pull 4x out of each term individually, so you would get
4x^3 + x + 2
