You can put this solution on YOUR website!
(y - 2/3)^2 = 4/9
(3y-2 / 3)^2= 4/9
9y^2-12y+4 /9 =4/9
9y^2-12y+4 =4
9y^2-12y=0
3y(y-4)=0
Either 3y=0 OR y-4=0
SO y=0
oR y=4

I need help finding the real solution to this equation.
(y - 2/3)^2 = 4/9

sqrt%28%28y+-+%282%29%2F3%29%5E2%29 = +-sqrt%284%2F9%29 ---- Take square root of each side
y+-+2%2F3%29 = +-2%2F3

y+=+%282%2F3%29+%2B+%282%2F3%29 or y+=+-%282%2F3%29+%2B+%282%2F3%29

highlight_green%28y+=+%284%2F3%29%29 or highlight_green%28y+=+0%29
