Question

Supply the missing number or term to make a perfect square trinomial.
y^2 + 8y +___

Answer 1

Essentially,we're looking for something that looks like this:
(y + k)^2
which, if we expand out, looks like this:
y^2 + 2k y + k^2

So, if we let that '2k' there be equal to 8, what would k be? We'd take that k-value and square it, and that'd be what we add.
