Factorize x2 – 3x + 4x –12
a) x2 – x – 12                        
b) x(x – 1) – 12 
c) (x + 4)(x – 3)                    
d) (x – 12)(x – 1) 

d

Solution: x2 – 3x + 4x –12
x (x – 3) + 4(x – 3)               = 
(x + 4)(x – 3)

Gradient = Vertical change(rise)/Horizontal change(run) Vertical change ? Vertical change=Gradient*Horizontal change Vertical change= 2*3 Vertical change=6

- Horizontal change (run) = 3 - Gradient (slope) = 2 Formula Gradient = Vertical change (rise) / Horizontal change (run) Rearrange the formula Vertical change (rise) = Gradient * Horizontal change (run) Calculate Vertical Change Vertical change = 2 * 3 Vertical change = 6 The vertical change is 6.
