**bobpursley**, Tuesday, March 2, 2010 at 8:17pm2(y^2-1/2 y -3)

add and subtract (1/4)^2

2(y^2-1/2 y +1/16 -3-1/16)=0

2(y-1/4)^2=6 1/8

(y-1/4)^2= 3 1/16=49/16

**drwls**, Tuesday, March 2, 2010 at 8:22pmThe subject is algebra, and it is not college level.

Start with

y^2 -y/2 = 3

To make the left a perfect square, add 1/16 to both sides.

y^2 - y/2 + 1/16 = 49/16

[y - (1/4)]^2 = 49/16

y - 1/4 = + or - 7/4

Add 1/4 to both sides for the two answers
