Complete the square to write the formula of a parabola to identify focus and directrix

The video tutorial explains how to convert equations from standard form to conic sections, focusing on identifying the vertex and the value of P. It covers completing the square to form a binomial squared, determining the graph's direction based on the value of P, and calculating the focus and directrix. The tutorial also discusses finding the axis of symmetry and provides step-by-step guidance on these processes.

What is the main goal when converting an equation from standard form to a conic section?

• To calculate the area under the curve

• To determine the vertex and value of P

• To find the slope of the line
