The document provides instructions for factorizing quadratic equations. It begins with examples of factorizing polynomial expressions. It then lists steps for factorizing quadratics in standard form using the difference of squares method. Students are assigned practice problems factorizing various quadratic expressions in their textbook. The learning objective is stated as factorizing quadratics with the difference of two squares method.
Factorise quadratic equations 3
- 1. Entry Activity Expand the following: 1) (e + 4)(e + 5) 2) (w + 2)(w – 3) 3) (f – 3)(f – 6) 4) (2d + 3)(3d + 6) 5) (4h – 2)(3h – 6) 6) (a – b)²
- 2. Today I will learn to factorise quadratic equations. Grade B Challenge Objective: To factorise quadratics with the difference of two squares Grade A
- 3. Things to remember Factorise means put in brackets. • x²+ ax + b = (x + ?)(x + ?) Since everything is positive. • x² – ax + b = (x – ?)(x – ?) Since –ve × –ve = +ve. • x²+ ax – b = (x + ?)(x – ?) Since +ve × –ve = –ve. • x²– ax – b = (x + ?)(x – ?)
