Question

Help..idk whats wrong with this question

Answer 1

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

Answer 2

is it already in simpliest form though?

Answer 3

or what..idk get how to simplify this

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

Maybe it wants you to multiply it out

Answer 11

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

Answer 12

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

Answer 13

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

Answer 14

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

Answer 15

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'

Answer 16

okay..thankyou

Answer 17

tricky though lol.

Answer 18

yeah. np

Answer 19

for this

Answer 20

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

Answer 21

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

Answer 22

ohh i see now. thankyou

Answer 23

could you tell me if this is correct?

Answer 24

Simplify: (2x+y)(2x-y)=

4x2-y2

Answer 25

yup

Answer 26

:) thanks again
