Hey Kyle, post again of no one answers within 12 hours - spamming of questions bumps your query down the line and out of sight. Note that the purpose of completing the square for quadratic functions is 1) to determine the line of symmetry. 2) to determine the min/max coordinate for the graph and 3) find the roots, when y = 0. Essentially, completing the square leads to the quadratic formula x = [-b +/- sqrt(b2 -4ac)] ÷ 2a
