Question

Long division of polynomial​

Answer 1

DescriptionIn algebra, polynomial long division is an algorithm for dividing a polynomial by another polynomial of the same or lower degree, a generalised version of the familiar arithmetic technique called long division. It can be done easily by hand, because it separates an otherwise complex division problem into smaller ones.

Answer 2

At the very first you have to write the polynomial in such way that their powers are in descending order..

Then, write the dividend and divisor in proper places.

After that, keep on the division method, and remember to change their signs as I have written in the pic (if its plus, change to minus and vice versa)...

well, check this example to understand more easily...
