Finding the fixed point.. I don't quite understand this question.
$f(x)=ax^2+bx+c$, where $a=14,b=−25$ and $c=−7$. There are two fixed points at $x_1$
and $x_2$, where $x_1>x_2$. How to get the value of $x_1$? In two decimal places.
Just click on the link below for my working, I think I got it wrong. Can someone help me on this?

let $x$ be a fixed point, then $f(x)=x$, solve this equation.
Or you can think of a function $g(x)=f(x)-x$ and find the roots
