The basic principle behind solving quadratic equations is... (dun dun dun...)

If two numbers (_________________) have a product of zero, then 

either one or both ______

Steps to Solve Quadratic Equations

1) Make sure all the numbers and variables are on one side of the equal sign so that the polynomial is equal to zero (should look like ax2 + bx + c = 0)

2) Factor (use common factors, difference of squares, trinomial or decomposition)

3) Set each factor equal to zero and solve for the variable
