Vocabulary : a 2 - b 2 is the difference of perfect squares. Factor x 2 -4x- The vertex and intercepts are also labeled on the graph. Subtract from both sides of the equation. Find the vertex and explain what it means in terms of dog pens. This can sometimes be used to solve quadratic equations. If a is negative , generally the graph looks like this: If a is positive , generally the graph looks like this:. Algebra gives the exact point where they intersect. Cancel the common factor. According to the graph, the rock is on the ground at zero seconds right before the boy shoots it and at 4 seconds when the rock lands. The P intercept 0. The quadratic formula, solves the quadratic equation. The B intercepts are 0. Find the vertex and explain what the vertex means in terms of making computer games.

Just for a moment let is pretend that the coefficient was negative. Find the mid point and that is the x coordinate for the minimum. Substitute back into the equation to determine the y coordinate.

The rock is 48 feet in the air at 3 seconds. The graphs of quadratic equations result in parabolas U shaped graphs that open up or down. The focus of a parabola can be found by adding to the y-coordinate if the parabola opens up or down. Do NOT wait until the night before to study. Two techniques for factoring are presented in this unit. Find the vertex. The Time Intercepts , 0, 0 and 4, 0 represent when the rock is on the ground. Find the value of using the formula. This example is called factoring the difference of perfect squares, and you will see this again if you take MAT , Intermediate Algebra. Vocabulary : Vertex: The vertex is the maximum or minimum point on the graph. Substitute the known values of and into the formula and simplify.
