Homework Statement
[tex]Let F(x) = (x-a)^2(x-b)^2 + x[/tex]. Show that the output [tex]\frac{a+b}{2}[/tex] exists for some value x.
Homework Equations
Quadratic formula. [tex]x^2 \geq 0[/tex].
The Attempt at a Solution
Hmm I've tried setting the two equal but that doesn't look nice (if I multiply everything out). It's easy to find the zeros of F(x) so there might be someway to relate to that? If someone could just give me a hint at a good first step for showing the existence of a certain output of a function.
