We have learned 5 methods/ways to solve quadratic equations: by factoring, by completing the square, by quadratic formula, by using square root/by squaring, and by graphing. Solve it 2 of the 5 methods / ways. You can pick whichever 2 methods you prefer, but it cannot be graphing. f(x) = 3x2 – 6x – 33 Method 1: Method 2: What do you notice about the two solutions you got?
