Question statement

Factorise the following quadratics

Give any introductory information the student needs.

			Name	Type	Generated Value

a	vector	vector(1,4,1,1,4)
b	vector	vector(2,1,-3,-4,5)
c	vector	vector(1,1,1,1,1)
d	vector	vector(3,3,1,-3,4)

Automatically regenerate variables?

Name

Data type

Value

xxxxxxxxxx
 
vector([1]+[random(2..4)]+[1]+[1]+[random(3..4)])

JME function reference

Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `vector`
