Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a non-negative integer. For example, 3x+2x-5 is a polynomial.  1.

It tells us the remainder when a polynomial is divided by \[x - a\] is \[f(a)\]. This means if \[x - a\] is a factor of the polynomial, the remainder is zero. It's a neat trick to quickly find remainders without doing long division! video https://cdn.kastatic.org/googleusercontent/A7Mn0-RlnewSTPhArUUEQdaveGrH5a8EdaO7Ns_HHm-WbeGRBt0rbt897PMxuhOGR1V53CjTKN_FYZ8gwjaNjOtI Intro to the Polynomial Remainder Theorem The Polynomial Remainder Theorem allows us to determine whether a linear expression is a factor of a polynomial expression easily.
