Today JPaul and I learned how to apply the Quadratic formula to solve quadratic equations. This is a review from Algebra 1, however JPaul said he has never seen the formula. So we Youtube'd a silly video/song to help him remember the formula. Then we looked at skill based questions. I reminded JPaul in order to use the formula, the equation must be set = to 0 first. He identified a,b,and c and was able to substitute their values into the formula and simplify correctly. Next, we looked at application problems. I showed JPaul how, if a golfball is hit and follows trajectory of a parabola upside-down. I explained to him where each coefficient comes from and how it affects the equation. We used the formula to find how long the ball is in the air for.
