When forming a perfect square trinomial you need to "complete the square". All of the steps to completing the square when solving an equation: 1. The leading coefficient must be 1. 2. Divide b by 2. 3. Square (b/2) 4. Add (b/2)^2 to both sides to keep the polynomial balanced. 5. You can now write the perfect square trinomial and solve.
yes he did make it, when he left at 17:00 he had 3:00 hours to make it to the party. if you divide 200/80=2.5 meaning he's able to make it in 2.5 hours.
