How to Divide Polynomials by Monomials and Binomials

TL;DR

To divide polynomials by monomials, divide each term in the polynomial separately by the monomial. When dividing by binomials, use long division, which involves arranging terms correctly and finding both the quotient and remainder. Always check your work by multiplying the quotient by the divisor to ensure accuracy.

Transcript

in this lesson we're going to divide a polynomial by a monomial so let's say if we have 12x to the fourth minus 9x cubed plus 15x squared all divided by a single term a monomial in this case 3x squared so what would you do to simplify this expression whenever you're dividing by a single term the best thing to do is to separate the fraction into sma...
