Expressions are mathematical statements without the equation sign
The possible integer values of q, r, and z are 3, -4 and -1
<h3>How to determine the values of the integers</h3>
The expressions are given as:
x^2 + zx - 12
(x + q)(x + r)
Both expressions are equal.
So, we have:

Expand

By comparison, we have:


Assume that q = 3.
So, we have:

Divide by 3

Recall that:

So, we have:


Hence, the possible integer values of q, r, and z are 3, -4 and -1
