Take HALF of the coefficient of y, which is 7, and SQUARE it to get 49. Add this to each side of the equation:
y^2 + 14y + 49 = 32 + 49
(y+7)^2 = 81
Take the square root of each side:
Calculate each value:
y=-7 +9 =2
y=-7-9 = -16

solve y^2+14y=32 by completing the square,..thnks
------
y^2 + 14y + (14/2)^2 = 32 + (14/2)^2
----
y^2 + 14y + 49 = 81
---
(y+7)^2 = 81
--
y+7 = 9 or y+7 = -9
y = 2 or y = -16
