If r and s be the remainders when the polynomial

and are divided by (x+1) and (x-2) respectively and 2r + s = 6Then find the value of a

P.S: Sorry it should have been x + 1

Is the answer 2 or something else?

put x = -1

Do a similar thing for the other and then substitute into the equation for r and s to get a

I just edited the last post there were errors

I am sorry for that

No worries. I've edited post 2 for this.

I make it a = -4/10 and I've checked it back in the cubics.

Maybe you should post your expressions for r and s.
