Suppose you divide a polynomial by a binomial. How do you know if the binomial is a factor of the polynomial? Create a sample problem that has a binomial which IS a factor of the polynomial being divided, and another problem that has a binomial which is not a factor of the polynomial being divided.

Question

Can someone give me an example of whats above plz. This is to help me study for a test that is coming up.

Answer 1

To be a factor, the division has to be exact, that is,
the remainder must be zero

works that way with numbers, works that way in algebra.
