Factorising a Quadratic Equation
All of these equations are quadratic equations y
x2 5x 6 y x2 3x - 10 y x2 - 16 y
x2 3x
y ax2 bx c A, b and c can be any numbers
2
To solve by factorising 0 x2 5x 6
FIRST Find all the factor pairs of 6
1 X 6 6 2 X 3 6
SECOND Choose the pair that add up to 5
2 3 5
THIRD These two numbers give the answer like
this 0 (x 2)(x 3) x -2 and -3
