Examples: 10pts Solve x2 + 8x + 8 = 0 by completing the square. Show and explain all the steps. Give examples of 4 different quadratic equations that would give 2 real rational solutions, 2 real irrational solutions, 1 solution, and 2 complex solutions. Write the equations and show how to solve them using the quadratic formula. Be sure to identify what kinds of solutions each equation has when they are solved. Put the following equations into vertex form and then them. Show and explain all of your steps. y = x2 + 8x + 16 y = -x2 4x -1 y = 2x2 12x + 17 – –
