## itsjustme_lol 2 years ago Help..idk whats wrong with this question

1. itsjustme_lol

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

2. itsjustme_lol

is it already in simpliest form though?

3. itsjustme_lol

or what..idk get how to simplify this

4. Scrambles

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

5. itsjustme_lol

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

6. Scrambles

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

7. Scrambles

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

8. h3rpd3rp

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

9. Scrambles

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

10. CalebBeavers

Maybe it wants you to multiply it out

11. h3rpd3rp

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

12. Scrambles

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

13. itsjustme_lol

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

14. itsjustme_lol

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

15. Scrambles

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'

16. itsjustme_lol

okay..thankyou

17. itsjustme_lol

tricky though lol.

18. Scrambles

yeah. np

19. itsjustme_lol

for this

20. itsjustme_lol

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

21. Scrambles

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

22. itsjustme_lol

ohh i see now. thankyou

23. itsjustme_lol

could you tell me if this is correct?

24. itsjustme_lol

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

25. Scrambles

yup

26. itsjustme_lol

:) thanks again
