Ruffini’s rule doesn’t rule all

Posted by ricardogm on 9th November 2017


Today we are going to use the quadratic formula to factor second degree polynomials. Sometimes, when you are using ruffini, you factor until you get a second degree polynomial. If this polynomial doesn’t have integer roots, you are not going to find them, but using the famous formula for second degree equations, you can get to them.

1. Use Symbolab to correct the exercises from yesterday. Call me if something doesn’t match.

2. Now try to factor these polynomials. In some of them you are going to need this method. Do it in your notebook, and use Symbolab to check your answers.


Halloween is over, but…
