sorry fail i do know how to do this .. but it is a long proof on the laptop ... so i'll give u the first part and u just need 2 follow tht method ...

2x+7 | 2x^4+21x^3+35x^2-37x+46

you need to make 2x become 2x^4 .. by multiplying it by something .. in this case x^3 .. so tht is ur first term;

2x+7 | 2x^4+21x^3+35x^2-37x+46
           2x^4 +7x^3               <- this is (2x+7)x^3 btw           (Long division method)
                      14x^3 - 35x^2

Then multiply 2x by something to make it become 14*x^3 .. this would be 7x^3 .. so tht is ur next term

By following this method you should get the equation
x^3+7x^2-7x+6 with no remainder
