Key Vocabulary / Formulas/ Things to Remember

Quadratic Equation:  equations in the form ax2+bx+c=0 

Greatest Common Factor or GCF:  the greatest factor that divides two numbers.  
Examples:  the GCF of 20 and 12 is 4, the GCF of 20x5 and 12x3 is 4x3 

Coefficients:  a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., the 5 in 5x) 

Zero Product Property:  If we multiply two (or more) things together and the result is equal to zero, then we know that at least one of those things that we multiplied must also have been equal to zero. (if a∙b=0, then either a = 0 or b = 0)
