Question

Square of binomial a - b is square of the first term plus square of second term minus twice the ______of the two terms​

Answer 1

The square of the binomial a - b is equal to the square of the first term (a) plus the square of the second term (-b) minus twice the product of the two terms (2ab).

Step-by-step explanation:

The square of the binomial a - b is equal to the square of the first term (a) plus the square of the second term (-b) minus twice the product of the two terms (2ab).

So, (a - b)² = a² - 2ab + b²

For example, if we have (3x + 2y)², the square of the first term is (3x)² = 9x², the square of the second term is (2y)² = 4y², and twice the product of the two terms is 2(3x)(2y) = 12xy. Therefore, (3x + 2y)² = 9x² - 12xy + 4y².
