You can differentiate and find the places where the differential is equal to 0, as these are the places where the curve is stationary.
You can only complete the square for quadratics. This approach finds the point on the curve that is midway between the roots, which also gives the maxima/minima. -

What's the difference between the minimum/maximum and the maxima/minima? -

maxima/minima - plural (e.g. cubics etc)
