Question

the product of three consecutives integers n-1,n,and n+1 is -336.what are the integers?HELP PLEASE

Answer 1

n-1 + n + n+1 = 3n

3n=-336
n=-113

Answer 2

THANK YOU!!!

Answer 3

(n - 1)(n)(n + 1) = -336

which gives:

n^3 - n + 336 = 0

Synthetic division gives n = -7, so your numbers are -6, -7, and -8

Answer 4

Aha, sorry ignore my answer @tcarroll010 has the right one, I thought it was a sum and not a product

Answer 5

can u show the step in synthetic division please

Answer 6

np @SmartWish you were definitely on the right track and just had a little lapse.

Answer 7

no problem,thank you for help me in this anyway!!!

Answer 8

You can go through synthetic division, or a much simpler intuitve way is to get an approximation of taking the third root of -336 and you will see that it is very close to -7.

Answer 9

yes you are definetily right

Answer 10

You could go through synthetic division to get the answer, but, believe it or not, you basically have to know the answer before actually doing the synthetic division!

So, in a case like this, it is much much much better to do the approximation.

Answer 11

thanks you help me a lot

Answer 12

Good luck to you and thx for the recognition!
