Today's class covered the following contents of factoring:
1) Factoring binomials
1) Factoring binomials
2) Solving quadratic equations by factoring
Zero factor property: if a and b are real numbers and ab=0, then a=0 or b=0
Thus, when a polynomial equals zero, if we can factor the polynomial, then each factor equals zero.
Be careful the polynomial has to be equal to zero:

3) Solving equations with degree greater than 2 by factoring. Usually you need to factor out the greatest common factor first.
