x cubed + 7x squared - 49 divided by x + 5

I know the answer is x squared + 2x - 10 + 1 over x + 5 but i dont know how to get that

x cubed = x^3

x squared = x^2

The first formula can be better written as:

(x^3 + 7x^2 - 49)/(x + 5)

The potential answer would be written as:

(x^2 + 2x -10 + 1)/(x + 5)

Why are the -10 and +1 combined? If (x + 5) is still in the divisor, how did you divide?

If this is the true answer, I don't know how to get from one to the other either. Do you have any typos in these formulas? If so, please repost with corrected formulas.

I hope this helps. Thanks for asking.
