# Math Help - Dividing Polynomials

1. ## Dividing Polynomials

Please help, i am confused over this, as you can see the exponent on the first term is 45,

Find the remainder when $3x^45+4x^8-5x^3+2$ is divided by $x+1$

The Remainder Theorem

3. 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?

try again ...

$3(-1)^{45} + 4(-1)^8 - 5(-1)^3 + 2$

5. -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
