Polynomial Division
Basics of Polynomial Division
Polynomial division is a process where we have two polynomials: the dividend (the polynomial we are dividing) and the divisor (the polynomial we divide by). The result is the quotient, which is also a polynomial, and in some cases we also get a remainder.
The Division Procedure
-
Arrange the polynomials First, we write both polynomials in descending powers of the variable.
-
Divide the leading terms We divide the leading term of the dividend by the leading term of the divisor. The result becomes the next term of the quotient.
-
Multiply and subtract We multiply the divisor by this term of the quotient and subtract that product from the current dividend. What is left becomes the new dividend.
-
Repeat the process We repeat the same steps with the new dividend. We continue until the degree of the new dividend is lower than the degree of the divisor.
-
Remainder If the degree of the current dividend becomes smaller than the degree of the divisor and we cannot continue dividing, the remaining polynomial is the remainder.
