Thanks to anyone who posts or can help !

A quadratic function has zeros -5 and 4. The graph of the function pases through the point (6,11).
Determine the equation of the function

This is so confusing to me..lol

Solve this system.
\(\displaystyle \left\{ {\begin{array*}{l}
{25a - 5b + c = 0} \\
{16a + 4b + c = 0} \\
{36a + 6b + c = 11} \\
\end{array}} \right.\)

It has roots x=-5 and x=4 so is of the form
y = a(x + 5)(x - 4)

Use the known point to find a.
