Which of the following is the product of (a + b)(a – b)?

The correct answer is  option B. a² - b²

Step-by-step explanation:

To find (a + b)(a – b)

(a + b)(a – b) can be written as,

(a + b)(a – b) = a(a -b) + b(a - b)

(a + b)(a – b) = a*a - a*b + b*a -b*b

(a + b)(a – b) = a² - ab + ba - b²

(a + b)(a – b) = a² - ab + ab - b²

(a + b)(a – b) = a² - b²

Therefore the correct answer is  option B. a² - b²

the answer is -1 1/5, also a
