Question

Which trinomial is a perfect square trinomial?

Answer 1

`y^(2) + 9y + 81`

Explanation:

A perfect square trinomial is an algebraic expression that is of the form
`ax^2 + bx + c`, which has three terms. It is obtained by the multiplication of a binomial with itself. For example,
`x^2 + 6y + 9` is a perfect square polynomial obtained by multiplying the binomial (x + 3) by itself.
