2. 2.1 Recognising Quadratic Equations Students will be taught to 1. Understand the concept quadratic equations and its roots. Learningt Outcomes Learningt Objectives Students will be able to: 1.1 Recognise quadratic equation and express it in general form
3. QUADRATIC EQUATIONS (ii) Characteristics of a quadratic equation: (a) Involves only ONE variable, (c) The highest power of the variable is 2. (i) The general form of a quadratic equation is ; a, b, c are constants and a ≠ 0. (b) Has an equal sign “ = ” and can be expressed in the form ,
5. Students will be taught to 2. Understand the concept of quadratic equations. Learningt Outcomes Learningt Objectives Students will be able to: 2.1 Determine the roots of a quadratic equation by 2.3 To Solve Quadratic Equations ( a ) Factorisation ( b ) completing the square ( c ) using the formula
6. Method 1 By Factorisation This method can only be used if the quadratic expression can be factorised completely. Example: Solve the quadratic equation
7. Example: Method 2 Formula a=2 , b =-8, c=7 x = 2.707 atau 1.293 Solve the quadratic equation by formula.Give your answer correct to 4 significant figures
8. Method 3 By Completing The Square Example 1: Simple Case : When a = 1 - To express in the form of Solve by method of completing square
9. Method 3 By Completing The Square Example 2: [a = 1, but involving fractions when completing the square] x = - 0.5616 x = 3.562 or - To express in the form of Solve by method of completing square
10. Method 3 By Completing Square Example 3: If a ≠ 1 : Divide both sides by a first before you proceed with the process of ‘completing the square’. 2.707 or 1.293 - To express in the form of Solve by method of completing square
