Factorising Quadratic Equations (Where a>1)

This lesson covers:

How to factorise quadratics where the coefficient of the $x$ ² term is 2 or more
E.g. 'Factorise 2 $x$ ² - 5x + 2'

Factorise the following quadratic:

2x2−5x+2

(2x-1)(x-2)|(x-2)(2x-1)

Factorise the following quadratic:

2x2−5x−3

(2x+1)(x-3)|(x-3)(2x+1)

Factorise the following quadratic:

3x2+5x+2

(3x+2)(x+1)|(x+1)(3x+2)

Factorise the following quadratic:

2x2+x−6

(2x-3)(x+2)|(x+2)(2x-3)

Factorise the following quadratic:

3x2+14x−5

(3x-1)(x+5)|(x+5)(3x-1)
