Factorising quadratics where a is not 1
A short video showing a quick method for factorising quadratic expressions where the coefficient of the x squared term is not 1. This is a quick method that allows the correct answer to be achieved without trial and error and guess work.
Examples:
2x2 + 9x + 4
3x2 - x - 2
12x2 - 11x + 2
GCSE Algebra Harder Factoring Quadratics Coefficient not 1
GCSE and AS Core 1 Mathematics Examples:
2x2 + 3x + 1 = 0
3p2 + 7p + 2 = 0
4x2 + 8x + 3 = 0
4u2 + 17u + 4 = 0
6p2 + 5p - 4 = 0
12r2 + 8r - 15 = 0
-6y2 - y + 2 = 0
2x2 - 3x + 1 = 0
4x2 - 23x - 6 = 0

GCSE to A Level Bridging Course Harder Factoring and Solving of Quadratic Equations
A video explaining how to solve a quadratic equation where coefficient of x2 is greater than 1.
Examples:
Factorise each of the following expressions:
3x2 + 8x + 4
5x2 + 3x - 2
x2 - 9 = 0
4x2 + x - 3 = 0
4/x - 6/x + 1/(x + 1) = 0
3x2 + 6x = 24
Solve the following equations correct to 2 decimal places each time.
x2 + 4x - 6 = 0
