Hi guys help if you can

1. Use long devision to divide:

6x^4+10x^3+13x^2-5x+2/2x^2-1

I know how to use long division, but for this one answears dont add up, im thinking maybe theres a type-o in it somewhere?, tried everything cant get anyform of answear out.

2. Use synthetic devision to divide:

5x^3+33x^2+50x-8/x+4

Ok for Q2 i got and wondering if its right, 5x^3+53x^2+162x+640/x+4
