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: `integer`

-5

This variable doesn't seem to be used anywhere.

Advice

$\frac{{\simplify{(n^2+({e1}+{e2})n+{e1}{e2})}}}{{\simplify{(n^2+({e1}+{e3})n+{e1}{e3})}}}$

In this question there is a quadratic expression which needs to be factorised into the products of binomials in both the numerator and denominator.

$\frac{({\simplify{n+{e1}}})({\simplify{n+{e2}}})}{({\simplify{n+{e1}}})({\simplify{n+{e3}}})}$

The repeated binomials in the numerator and denominator cancel, leaving:

$\frac{({\simplify{n+{e2}}})}{({\simplify{n+{e3}}})}$
