Transcript Lesson 6.8
6-8 Solving Equations by Factoring
How to Solve
1. Factor your problem using the best method if needed
2. If the problem says =0 set each parenthesis equal to 0 and
solve for the variable
3. If the problem says =number, move the number to the
other side, factor then solve for each parenthesis
If there is no equal sign, set the problem equal to 0, factor
then solve each piece.
