Please help, i am confused over this, as you can see the exponent on the first term is 45, Find the remainder when $\displaystyle 3x^45+4x^8-5x^3+2$ is divided by $\displaystyle x+1$

so i get b=(-1) so when i insert -1 into the equation i end up with an answer of 0. So i get no remainder then, is that right?

-3+4+5+2 = remainder 8 Thanks for your help, i just got so confused over the high exponent, i was thinking i had to use synthetic division, and add a bunch of zero's
