Simplify: (2x+1)(3x^2+2x+1)=

- anonymous

is it already in simpliest form though?

- anonymous

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

- anonymous

well how am I suppose to know if im looking for imagenairy roots? its says nothing but to simplify that...weird!!!

- anonymous

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

- anonymous

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

- anonymous

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

- anonymous

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

- anonymous

Maybe it wants you to multiply it out

- anonymous

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

- anonymous

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

- anonymous

hmmmmmmmmmmmmmm...i wonder what i should chose for my answer

- anonymous

because i totaly agree with what both of you are saying though

- anonymous

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'

- anonymous

okay..thankyou

- anonymous

tricky though lol.

- anonymous

yeah. np

- anonymous

for this

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

- anonymous

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

- anonymous

ohh i see now. thankyou

- anonymous

could you tell me if this is correct?

- anonymous

Simplify: (2x+y)(2x-y)=
4x2-y2

- anonymous

yup

- anonymous

:) thanks again
