Answer:


(1)/(4)

Explanation:

Let us see the standard form of an quadratic equation converted form of complete square .


(a+b)^2=a^2+2*a*b+b^2

The first two terms given are


y^2+y\\=y^2+2*(1)/(2)*y

Hence comparing it with our standard form

The constant term must be the square of the middle term. That it
((1)/(2))^2=(1)/(4)
