Algebra 2 10/19/16 EQ: How do I complete the square to solve for x? HW: pg 345 # 1-31 odd Copy Know it Box on pg 343 in your notes and copy example 4 A and B in your notes (including blue writing) Warm up: See board

2. Solve for variable
(x + 5)2 = 9 (x - 2)2 = 36 (x + 1)2 = 18

3. Complete the square
Goal From: To: ax2 + bx + c = (x + a)2 = x2 + 6x +

4. x2 - 12x +

5. 4x2 - 48x +

6. Solve by completing the square
x2 -12x + 20

7. Solve by completing the square
3x2 +18x – 45 = 0

8. X2 - 6x = -4

9. 2X2 + 16x – 10 = 30

10. Deriving the quadratic formula
ax2 + bx +c = 0
