Study the lesson, "Completing the Square to Solve General Quadratic Equation". Find it through the lessons link in my profile.
First factor the from the quadratic expression, and then add and subtract the missing square term.
is the factored form, and then the square term to add and subtract on the INSIDE of the parentheses is . The lesson explains everything more thoroughly.
