Frequently Asked Questions

What is the identity of (a - b)²?

The identity is (a - b)² = a² - 2ab + b². It states that the square of a difference equals the square of the first term minus twice the product of both terms plus the square of the second term.

Is (a - b)² equal to a² - b²?

No. The correct expansion is (a - b)² = a² - 2ab + b². The expression a² - b² represents the difference of two squares and can be factored as (a - b)(a + b).

Can I use negative numbers in this calculator?

Yes, the algebraic identity works with negative numbers as well, provided the calculator accepts negative inputs. Remember to use parentheses when substituting negative values to avoid sign errors.

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

The expansion of (a - b)² is a² - 2ab + b², whereas the expansion of (a + b)² is a² + 2ab + b². The middle term is negative in the first identity and positive in the second.

Who can use the A Minus B Whole Square Calculator?

School students, college students, teachers, and anyone practising algebra can use this calculator to expand expressions and verify calculations involving the square of a difference.
