Note: There will be some extra steps because the coefficient of z is not 1. y = 572 – 17x – 3 - Step 1: Separate non-x-terms from x-terms Manipulate the equation until all terms containing z are on one side of the equation, and all terms containing z are on the opposite side: = 572 - 17r y+3 - Step 2: Divide off the coefficient of z y + 3 = 52? – 17z There's a slight problem with completing the square at this point, and it's because we have a coefficient of z? that's not 1. Divide both sides of the equation by 5 so that we can proceed with completing the square. (1/5)y+3/5 = (5/5)x^2-(17/5)x - Step 3: Identify the value that completes the square Now that we've removed the coefficient of z?, what value completes the perfect square trinomial? z² - 17+ 289/100 - Step 4: Complete the Square + = x? - r Add 2 to both sides to complete the perfect square trinomial. 100 = x? - r+ m 289 100 (20y+349)/(100) * Step 5: Factor and start solving for y 349 + 100 Factor the perfect square trinomial, and begin solving for y. Step 6: Finish solving for y Step 7: Identify the vertex
