Check whether the given trinomial is a perfect square or not.

Answer to Problem 85S
The given trinomial is a perfect square.
Explanation of Solution
Given:
The given trinomial is
Calculation:
For perfect trinomial, the first and last terms need to be perfect squares and the middle term needs to be twice the product of the square roots of the first and last terms.
In the given trinomial
the first
Middle term
Check
