Set equation = 0 Factor Completely Set each factor = 0 and solve. Set equation = 0 Factor Completely Set each factor = 0 and solve. Solution 4. 8x + 24 < 2x2 Solutions 5. x² + 4x + 3 < 0 Equation 6. Roots are at x = -5 and x = -2/3 Find the quadratic function Set equation = 0 Set equation = 0 Start with your factors in x= Set the equations = 0 Factor Completely Factor Completely Remove any fractions by multiplying the equation by the denominator Set each factor = 0 and solve. Test a point to determine shading Set each factor = 0 and solve. Place in Factored Form and multiply out Sage-N-Scribe Kagan Activity: Problem 1 - Student A is the Sage; Student B is the Scribe. 1. The Sage gives the Scribe step-by-step instructions on how to solve problem #1 2. The Scribe records the Sage’s solution step-by-step in writing 3. If the Sage is correct, the Scribe praises the Sage. Otherwise, the Scribe coaches, then praises. 4. Students switch roles for the next problem. (at the end, each student will have one problem worked out on their paper, which they will glue in their notebook) #1. #2. Solve the quadratic function Solve the quadratic function x2 + 8x = -15 12x2 + x = 1
