Calculadora de Quadrado de Binômio

The Binomial Square Calculator solves expressions of the form (a + b)² and (a - b)², automatically expanding them to a² + 2ab + b² or a² - 2ab + b². You enter the values of a and b, and the tool calculates the result step by step, showing the algebraic development. It is useful for algebra students who need to check exercises or understand the application of the formula.

The operation is simple: the calculator applies the identity (a ± b)² = a² ± 2ab + b². First, it squares a, then calculates twice the product of a and b (with a positive or negative sign as appropriate), and finally squares b. The result is displayed in an organized way, making it easy to verify.

Use this calculator when solving problems on special products, simplifying quadratic expressions, or checking manual calculations. It is especially useful for middle and high school students, teachers preparing examples, or anyone who needs to expand binomials quickly.

Caution: ensure that the values of a and b are correct. The calculator considers signs exactly as typed; if you enter (x - 3)², you must set a = x and b = 3, and select the subtraction option. Remember that the formula only applies when the expression is a binomial squared, not for higher powers.
