Lesson Plan : Quadratic expressions
Teacher Name: | Sailor M. |
Grade: | College/University |
Subject: | Math |
Topic: | Factorising Quadratic expressions |
Content: | squared term (term in x2), term in x, constant term, highest power of x is 2, coefficients, factorisation |
Goals: | To identify a quadratic expression from a linear or other expressions To factorise a quadratic expression, where the constant term is zero |
Objectives: | To factorise such a quadratic expression by taking out the HCF from the two terms. |
Materials: | Counts 4, whiteboard |
Introduction: | |
Development: | A linear expression in x is of the form ax+b, where a and b are constants. The highest power of x is 1. For example: 3x-5, 2.4-6x, A quadratic expression in x is of the form ax2+bx+c, where a, b and c are constants but a=0, i.e. it should contain the term in x2. For example: 3x2 2x2+3 4x2-x+1 5+8x-x2 |
Practice: | Factorise: a)x2+3x b)x2-7x c)2x-x2 d)2x2+6x e)5x2+20x f)12x2-18x |
