• Students will be able to: film a video of a quadratic real-world situation, use the video of half of a quadratic to write the equation of the situation, and use the video of half of a quadratic to predict the rest of the quadratic and solve a real-world problem
• Graph the quadratic equation y = -x 2 + 2x + 3. We know what we have to find, so let's find it. 1. What are the intercepts? First, the x-intercepts. We need to find the roots of the quadratic polynomial. If we find them, we can celebrate by drinking a root beer. We need to find the solutions to the equation. 0 = -x 2 + 2x + 3 = -(x 2 – 2x – 3).
• MM1P1. Students will solve problems (using appropriate technology). a. Build new mathematical knowledge through problem solving. b. Solve problems that arise in mathematics and in other contexts. c. Apply and adapt a variety of appropriate strategies to solve problems. d. Monitor and reflect on the process of mathematical problem solving. MM1P2.
• Solve the quadratic equation using the quadratic formula: 9𝑥2+3𝑥−2=0. THE DISCRIMINANT • When we use the quadratic formula, it not only generates the solutions to a quadratic equation, it also tells us about the nature of the solutions. The expression under the radical, , is known as the discriminant.
• Pre-Algebra and Algebra. When you find yourself stuck with too many variables, use these explanations and tutorials to help you simplify. Learn all the major algebraic properties and find plenty of example problems.

Many Word problems result in Quadratic equations that need to be solved. Some typical problems involve the following equations: Quadratic Equations form Parabolas: Typically there are two types of problems: 1. Find when the equation is equal to zero. 2. Find when the equation has a maximum (or minumum) value. Solving Quadratic Equations by Factoring - These quadratic equations are not so simple, and we must use our factoring skills in order to solve. Using the Quadratic Formula - When in doubt, we an always use the quadratic formula to solve a problem! Learn how to use this very special formula.
