Perfect squares are simply numbers that can have their square roots taken without any decimals after words. Some numbers that have perfect squares are 4, 9, 16, 25 and 36. With a number like 5, if it has its square root taken, it will have whats called an irrational number. The square root of 5 is about 2.36067...etc.
You can also think about it in terms of squared numbers. With the number 1, if it's squared, the result will be 1. If you have 2^2(^ means the first number to the power of the number after the "^") So, 2^2 = 4, which is a perfect square. 3^2 = 9; 4^2 = 16 and so on. Anyone else have anything to add?

You really need to describe more specifically what it is you're trying to do.

I'm going to assume it has something to do with (x+1)^2 and not 2x2 squares, but you need to post maybe an example problem, and I can walk you through it.

A perfect square is any number that, when taking the square root, will produce a real number.

For example, 26 is not a perfect square because when taking the square root of 26, it gives you a number with decimal places. In other words, there are no SAME TWO numbers that when multiplied together will produce 26.

On the other hand, 100 is a perfect square because when taking the square root of 100 you get a real number, the number 10. In other words, since 10 times 10 = 100, then 100 is a perfect square.

How about 25? Yes, because 5 times 5 = 25.

How about 36? Yes, because 6 times 6 = 36.

Is this clear?
