This is the problem:(adsbygoogle = window.adsbygoogle || []).push({});

A quadratic function f(x) with integral coefficients has the following properties: [tex]f(3/2)=0[/tex], (x-2) is a factor of f(x), and f(4) = 50. Determine f(x).

The answer in the back of the book is [tex]f(x)=5(2x-3)(x-2)[/tex]

I can easily understand the (2x-3) and (x-2), but I don't understand the "5", and "f(4) = 50".
