Lesson 4-Zeros of the Quadratic Functions

A. Subject Title: Mathematics

B. Lesson No. 4

C. Lesson Title: Zeros of the Quadratic Functions

D. Lesson Outcome:

At the end of the lesson, the student is expected to:

• Determine the zeros of quadratic functions by factoring & quadratic formula.
• Relate the zeros of quadratic function to the roots of quadratic equation
• Determine the nature of the zeros

E. Review of the Previous Lesson:

General Form of Quadratic Functions

X-intercepts

F. Lesson Presentation:

The zeros of the quadratic function , y = ax^2 +bx+c are the roots of the quadratic equation,ax^2+bx+c = 0. These are the x-intercepts of the graph which can be solved algebraically by factoring & quadratic formula.The nature of zeros can be determined by discriminant .
