The Franklin Lee Middle School Glee Club is hosting a Talent Show competition to raise money for a community that was recently hit by a flood. All the members are asked to go out in the community to sell tickets to the show. ● Patrick sold 30 more tickets than Jose.
● Gabriella sold 25 less than two times the amount Patrick sold.
● Owen sold a third of the amount of tickets than Patrick sold.
● Desmond sold 15 less than Owen.
If Jose sold 30 tickets, how many tickets did each of the others sell?

To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex.
