Hello,

I want the wolfarmalpha website to solve this equation $h(v-t) = h(v+t) $ for $v$ where $h(x) = ax^2 +bx+c$. The $v$ is the vertex of the parabola I want the students to figure out what is the vertex for a general parabola. When $a,b$ and $c$ are numbers the website can solve that easily.

Any ideas of other websites which can solve that?

Thanks.
