To find the missing number or term to make a perfect square trinomial, follow these steps:

Take half of the coefficient of the middle term (8y), which is 4.
Square the result from step 1, which gives 16.
Add the result from step 2 to both sides of the trinomial.

The missing term to make a perfect square trinomial is 16.

So, the perfect square trinomial is: y^2 + 8y + 16.
