 After going through this lesson, you are expected to illustrates quadratic equations and solves quadratic equations by: (a) extracting square roots; (c) completing the square; and (b) factoring; (d) using the quadratic formula. You learned about linear equation in one variable which id in the form of ax + b- 0, where a is not 0 otherwise the equation is constant. Quadratic equation is in the form of ax? + bx + c = 0 and a cannot be zero otherwise the equation will become linear equation. Learning Task 1. Group the given equations into two based on observed common properties. na - 3n + 10 -0 8-3k- 12 2y --9 2x + 2x + 1 -0 25b- 16 -0 3r + 2e- -6 5w +5-0 a- 31 + 2 = o d- 3e-7 + 2m-4 10u - 5- 8 a- 225
