Lesson 5b - Solving Quadratic Equations Mini-Lesson Work through the following problem to put the solution methods of graphing, factoring and quadratic formula together while working with the same equation. Problem 12 YOU TRY – SOLVING QUADRATIC EQUATIONS Given the quadratic equation x 2 + 3x – 10 = 0, solve using the processes indicated below. a) Solve by graphing (use your calculator and the Intersection process). Draw a good graph, label the x-intercepts, and list your final solutions using proper notation. b) Solve by factoring. Show all steps as previously seen in this lesson. Clearly identify your final solutions. c) Solve using the Quadratic Formula. Clearly identify your final solutions. Scottsdale Community College Page 226 Intermediate Algebra
Name: _____________________ Date: ________________ Lesson 5b Practice Problems 1. Use your graphing calculator to help you determine the number and type of solutions to each of the quadratic equations below. a) Begin by putting the equations into standard form. b) Draw an accurate sketch of the parabola indicating the window you used. c) IF your solutions are real number solutions, use the graphing INTERSECT method to find them. d) Use proper notation to write the solutions and the x-intercepts of the parabola. e) Label the x-intercepts on your graph. a) x 2 – 6x + 9 = 0 b) 5x 2 + 4x – 5 = 0 c) 2x 2 – 4x = 3 d) 3x 2 + 6x + 4 = 0 Scottsdale Community College Page 227 Intermediate Algebra
