SOLVING QUADRATICS BY FACTORISING AND EQUATION
1. Solve by factorising:
a) x2 +4x – 5 =0
b) 4a2 – 3a – 10 = 0
2. Solve x2 – 5x + 2 = 8
3. Solve the following by using the formula:
a) x2 + 2x – 1 =0
b) 2x2 = 10x – 4
5. Write down quadratic equations with solutions as follows:
a) x = 2 and x = 5
b) x = -3 and x = 1/5
