Lesson 5b - Solving Quadratic Equations Mini-Lesson Problem 7 WORKED EXAMPLE–SOLVE QUADRATIC EQUNS USING QUADRATIC FORMULA Solve the quadratic equation by using the Quadratic Formula. Verify your result by graphing and using the Intersection method. Solve 3x 2 – 2 = -x using the quadratic formula. 1. Set to zero and write in standard form 3x 2 + x - 2 = 0 2. Identify a = 3, b = 1, and c = -2 3. (1) x (1) 2 2(3) 4(3)( 2) 1 1 ( 24) 6 1 1 24 6 1 6 25 4. Make computations for x 1 and x 2 as below and note the complete simplification process: 1 25 1 5 4 So, x 6 6 6 1 25 1 5 6 x 6 6 6 1 2 2 3 1 Final solution x = 2 , x = -1 (be sure to verify graphically…you may also need to obtain a 3 decimal approximation for a given value depending on how you are asked to leave your final answer) Graphical verification of Solution x = 2 3 Graphical verification of Solution x = -1 [Note that 2 . 6666667 ] 3 You can see by the graphs above that this equation is an example of the “Case 2” possibility of two, unique real number solutions for a given quadratic equation.
