Fill in your given numbers:
Square of a Binomial
This is about the basic operations of simple binomials. It is a common square calculation of two terms in brackets that requires you to calculate each value with each other. But to make life easier there is a shortcut.
(a + b)² = a² + 2 • a • b + b²
(a - b)² = a² - 2 • a • b + b²
(a + b)(a - b) = a² - b²
Instead of making the full calculation, you only need to put the values from the left side of the equation into the right side of the equation.
Sounds confusing? Don’t worry! The calculator shows both approaches.
