Standard form and identify the vertex of a graph

[mathmom]

I am trying to help my son with some homework, but we are stuck on a few problems. One is....

Write the standard form and identify the vertex of the graph of the quadratic function f(x)=5x^2+10x-13 by completing the square.

Write the standard form and identify the vertex of the graph of the quadratic function f(x)=5x^2+10x-13 by completing the square.

this is a skill learned during an intermediate algebra course, well prior to calculus.

have him research the method of completing the square to get the quadratic into the vertex form \(\displaystyle f(x) = a(x-h)^2 + k\)
