Polynomial Division works the same way as base-ten long-division. The powers of x are used instead of place value powers of 10.

How many times does x go into x^2?

Show x above the first term of the dividend.

________________________x
________________________________________________
________________|
____x+3_________)______x^2______-7x________+10

Multiply and then subtract....

________________________x
________________________________________________
________________|
____x+3_________)______x^2______-7x________+10
_______________________x^2______3x
__________________________________
_______________________0_______-10x

Bring down the next term, and continue the process...

________________________x________-10
________________________________________________
________________|
____x+3_________)______x^2______-7x________+10
_______________________x^2______3x
__________________________________
_______________________0_______-10x________10
_______________________________-10x________-30
_________________________________________________
________________________________0__________40

The degree of the remainder is less than the degree of the divisor, so the quotient found is
