We learned how to solve various forms of quadratic equations: solving using square root method, factoring and solving trinomials when a=1, factoring & solving by grouping, factoring & solving trinomials when "a" does NOT equal 1 and factoring & solving a difference of perfect squares. We didn't quite complete all of the notes in class (we will complete them in class on Monday before we take the quiz on graphing & characteristics). Below are the videos of the notes from Friday.
Video #1: solving by square root method and factoring & solving trinomials when a=1:
Video #2: Factoring & solving by grouping and factoring & solving trinomials when "a" is NOT 1:
Video #3: Solving difference of square by factoring & by square root method.
