"Quadratics is real simple." (1/18/08) - thoughts by Sir

Today we prepared for a test or assessment on quadratics. When you think about it, quadratics is real simple. Learn how to graph, find a curve of best fit, and use these four equations. y =a(x-h)^2 + k to find a, y = -b/2a to find b, y = ax^2 + bx + c to find c, and x = (-b +- radical b^2 - 4ac)/2a to find roots. With those 4 equations you can answer almost any question about that graph and equation. After achieving an "A" on that test with ease and a calculator I think the power of 17 may be more interesting and easier than WE ALL THOUGHT.
