What is the constant term that completes the perfect square trinomial. y^2 + y

Y^2 + y

y^2 + y + 0.25 < = = = the constant term is 0.25

(y + 0.5) (y + 0.5) =

(y + 0.5) ^2

to find the constant, u take half of ur y coefficient (not the y^2 coefficient) ... y^2 + 1y ... ur y coefficient is 1 ... half of it is 0.5 ... u then square it ... (0.5^2) = 0.25 ... this is ur constant
