Mathematics SSS 1 Second Term

WEEK 1

Factorization of Quadratic Expression of the Form ax² + bxc where a, b, c are constant.  

Performance Objectives

Students should be able to;

1. Factorize quadratic expressions.
2. Solve quadratic equations of the form ab = 0, i.e. a = 0 or b = 0.
3. Construct quadratic equations with given roots
4. Solve problems involving quadratic equations.

Revision of Linear and quadratic expressions

Content

Any expression in which the highest power of the unknown is 1 is called a linear expression.

Examples

a) x + 1

b) 2y + 3

c) p = −1/2

In general, linear expressions are expressions of the form ax + b, where a & b are constants and x is a variable.
