(3x+5)^2

Explanation:

This is a special product - a square of a binomial. So what you do first is to get the square root of the first term. You must get the square root of 9x^2 which is 3x. Then, you get the square root of 25 which is 5. Put them together but leave a space in the middle for the sign. Since the middle term is positive, we put a plus sign so the final answer is (3x+5)^2.
