: I have always had a problem dividing can someone help me solve this equation.... thank you very much
3x^4+11x^3-20x^2+7x+35/x+5
I can do sythetic division which would be x+5 divided into the problem above I have done it but the answer I got seems too long.. I got 1300 over x+5 using synthetic division.... can someone help me.

You can put this solution on YOUR website!
When you are dividing by x+5 you start the process with -5.
because you are testing the root x=-5 and you are finding
f(-5) which in your problem turns out to be zero, indicating
that -5 is a root and x=5 is a factor of your 4th degree
polynomial.

I have put in the intermediate step in the synthetic
division process. Does that help you understand
how I arrived at the Quotient and Remainder?
