In today's first topic you'll practice solving quadratic equations using the quadratic formula. The quadratic formula is probably the most common method for solving quadratic equations. As you work though this section please understand how the discriminant can help you decide how many and what kind of solutions you should expect. Today's second topic puts the quadratic formula to work as you apply quadratic equations. This material is covered on pages 313-326 in the Engaging Algebra textbook.
7.2 The Quadratic Formula
After finishing this work you'll be able to solve quadratic equations using the quadratic formula. You'll also be able to use the discriminant to predict the number of solutions and the type of solutions you expect.
7.3 Applying Quadratic Equations
After mastering this section you'll be able to use quadratic equations to answer "real world" questions.
