Using the AC-Method to Factorize Quadratic Equations
Evaluation
Based on the content covered kindly complete the activity below. You will be grade on the application of the AC method when solving the equations and how well you are able to utilize the graph sketch software to plot the graphs.
1. Solve the following equations:
a. 5 x 2+13 x=-6 b. 3 x 2 -17 x-16=0 c. x 2+6 x+5=0
2. Upon completion use the graph sketch software below to plot each of equations above in 1 above.
3. (a) In groups of four formulate a quadratic equation and solve it.
(b) Represent the information from the quadratic equation you have formulated on a graph using the graphsketch software.
(c) Present the information (Orally) to your classmates giving a detailed analysis of the graph and equation.
