(a ± b)² = a² + 2ab + b²
This expression applies the distributive property of multiplication to expand the square of a binomial containing two terms, a and b.
The expansion can be performed using the FOIL method:
(a ± b)² = a² + 2ab + b²
Expanded form:
(a ± b)² = (a + b)(a - b)
Examples:
(2 + 3)² = 4 + 12 + 9 = 25
(4 - 5)² = 9 - 20 + 25 = 9
(6 + 7)² = 36 + 49 = 85
