this is a gem

I need help finding the right practice exercises. [John bought 100 feet of fencing. What is the largest area he can make if his house is one side and the fencing makes the other 3 sides?] ----- #1.} X(100 - X) ----- #2.} 100X - X² ----- #3.} Negative 2X² + 100X ---- #4.} Applying the Axis of Symmetry, -B/2A, makes X = 50ft. -----#5.} Now I plug Known X into -X² + 100X to get Known Y, which is 2500 The Vertex is (50, 2500), which means two sides of the fence are 50 feet-----#6.} Next, I apply Known X into 100-X, which will give the remaining side, which is 50 feet. So the area is 50ft*50ft] What are these types of problems called?

if you add 18 on the left side you also add 18 on the right side. so the right side must be 22+18=40.

got it. ok

Factoring is quicker than quadratic formula. The quadratic equation is factorable
