Polynomial division is very similar to long division that we
learned in elementary school. Instead of simply using numbers, there are
variables as well. The process, though, is effectively the same. We go through
the problem term by term, just like in standard numerical long division. If we
understand how to do one type of long division, it is quite easy to extend the
technique to the other type of division. As long as we know how to multiply
monomial terms with variables, the actual process is the same. The polynomial
goes to the inside of the division symbol, and the binomial goes outside. We
try to get the first term of polynomial from the binomial first term, and
repeat this till we are able to get a polynomial of lesser degree than binomial
(remainder) or till we get zero remainder. Example (x^2 + 5x + 6) divided by x
+ 5 We get X+5 /x^2 + 5x + 6 First we multiply by x to get x^2 + 5x We get X +
5/ x^2 + 5x + 6 -x^2 – 5x 6 We get the remainder as 6 Here quotient is x and
the remainder is 6 If we divide same polynomial by x + 2 We get X+2 /x^2 + 5x +
6 First we multiply by x to get x^2 +2x, and then by 3 to get x + 6 We get X+5/
x^2 + 5x + 6 -x^2 – 2x X + 6 -x – 6 Zero remainder The quotient is x + 3 and remainder
0
