Question

For what value of b will the polynomial P(x)= 4x³-3x²+bx+6 have the same remainder when it is divided by (x-1) and (x+3)

Answer 1

this requires the same knowledge as the last question you posted: http://openstudy.com/updates/506384e5e4b0583d5cd38258

but you seemed to have closed that question without responding - does that mean you know how to solve it?

Answer 2

no i thought i posted the wrong question

Answer 3

so, do you know what the remainder theorem states?

Answer 4

yes, but i dont have the value of b nor do i have the value of the remainder

Answer 5

given some function f(x), what does the remainder theorem say the remainder will equal if f(x) is divided by (x-a)?

Answer 6

it will equal zero

Answer 7

no - you need to first understand this theorem properly

Answer 8

have a look here to brush up on it: http://www.purplemath.com/modules/remaindr.htm

then come back and try this question again.

let me know if you are still stuck after this and I will try and guide you further.
