  1. Section 5.5 Quadratic Equations Obj: to solve by factoring and by finding the square root.

  2. When you solve an equation---you are actually find the x-intercept of the graph. Linear Equations Quadratic Equations • 3x + 4 = 6x + 10

  3. Solve by factoring • Ex. 1 2 - 11x = -15 • Ex. 2

  4. Ex. 3 2 • Ex. 4 16 = 8x

  5. Solve by finding the square root. • Ex. 1 5 - 180 = 0 Ex. 2 4 - 25 = 0

  6. Ex.3 3 = 24 • Ex. 4 - = 0

  7. Assign: Pg 266 # 1-18
