Question 962772
solve this quadratic equation using completing the square method? 
x^2+5x+6=0
-----------
x^2+5x = -6
a = 1, b = 5
Add (b/2a)^2 to each side
x^2 + 5x + (5/2)^2 = -6 + (5/2)^2
x^2 + 5x + 25/4 = -6 + 25/4 = 1/4
(x + 5/2)^2 = (1/2)^2
x + 5/2 = 1/2
x = -2
================
x + 5/2 = -1/2
x = -3
