How do you find the quotient in polynomial long division?

Back

The quotient is found by performing the division of the leading terms and then multiplying the entire divisor by this quotient term.

What is the role of the remainder in polynomial long division?

Back

The remainder is what is left over after the division process is complete; it can be zero or a polynomial of lower degree than the divisor.
