Solve Quadratic Equations

Basic Factoring and Solving of Quadratic Equations - GCSE to A Level Bridging Course
Factorise the following:
x2 + x - 12
Solve the following: x2 - 25 = 0
2x2 - 71 = 0
(x - 6)(x + 5) = 0
x(3x - 2) = 0
2x2 + 3x = 0
4x2 - 25 = 0
x2 - 8 = 2x

Harder Factoring and Solving of Quadratic Equations
Factorise each of the following expressions:
3x2 + 8x + 4
