When we are given a quadratic function of the form:
[tex]f(x)=ax^2+bx+c[/tex]
We can solve for:
[tex]ax^2+bx+c=0[/tex]
Using the quadratic formula:
[tex]x_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Since we want to find the x-intercepts, these are the x such that f(x) = 0. The function given in the problem is:
