PLEASE HELP Consider the quadratic expression $13x^2 + nx - 17.$ For certain values of $n,$ it may be factored into a product of two linear polynomials, both of which have integer coefficients. What are all such values of $n?$

A quadratic equation that is factored into linear polynomials is of the form where a, b, c and d are integers. The possible values of n are 220, -220, -4 and 4.

Let the expression be:

So:

Multiply the coefficients of x^2 (13) and the constant (-17)

List out all prime factors of k

Add the factors to give the possible values of n

Hence, the possible values of n are 220, -220, -4 and 4
