Quadratic Formula
Factoring
Always check to see if you can factor
out a greatest common factor before
you do any other factoring!!
"6 + 2" + 6 = " + 6
"6 − 2" + 6 = " − 6
"6 − 6 = " + " − "6 + 6 =PRIME (does not factor)
Note: This is true, ONLY IF the greatest
common factor has already been
factored out.
"8 + 8 = " + "6 − " + 6
"8 − 8 = " − "6 + " + 6
If " 6 + + 7 = 0 and " ≠ 0 then
− ± √ 6 − 4"7
