Mixed Review of Solving for Roots - Jeanmarie Mullen | Library

Solve by FACTORING.   
Look for a GCF, then look to see if it is a trinomial, or a binomoial(DOTS)(Difference of perfect squares).

How to pick the best method.  
Before each question, plug the equation into the calculator.  

Roots are integers, then factoring may be the best way to solve for roots.  
Roots are decimals, then use completing the square or the quadratic equation. 
If the "a" value is not 1, you must use the quadratic equation.
