Frequently Asked Questions

What is the whole square identity?

The whole square identity for the sum of two terms is (a + b)² = a² + 2ab + b².

What is the difference between (a + b)² and a² + b²?

The expression (a + b)² includes an additional middle term, 2ab. Therefore, (a + b)² = a² + 2ab + b², not simply a² + b².

Can I use negative numbers?

Yes. The calculator can be used with positive or negative values, provided the input fields accept those numbers.
