Question

if x^-1 is a factor of ax^+bx*+cx^+dx+e show that a+c+e=b+d.

Answer 1

@apoorvk

Answer 2

why are you missing the indices, you need to mention the power. not just "ax^".

Answer 3

ax^ means raised to 2

Answer 4

@apoorvk

Answer 5

lol then write '2' next to '^'.
and cx^ means cx^2 as well? as for "dx*"??

Answer 6

dx*3

Answer 7

I seem to think that it's ax^4 actually - isn't it?

Answer 8

no ax^2

Answer 9

well, the the whole equation is basically:
\[bx^3 + (a+c)x^2 + dx + c\]
right?

that means 1/x completely divides this polynomial.

Answer 10

ya

Answer 11

brb

Answer 12

hmm

Answer 13

@apoorvk u derrr

Answer 14

yeah, so divide this polynomial by '1/x'! and get the remainder in terms of a,b,c,d,e and equate that to zero. Now rearrange that, and you 'll get the statement to be proved!!
