Question

Sum of two terms product and three terms product and so on

Answer 1

Answer:

(a + b) (a – b) = a(a – b) + b (a – b)

= a2 – ab + ba + b2

= a2 – b2

Therefore (a + b) (a – b) = a2 – b2

(First term + Second term) (First term – Second term) = (First term)2 – (Second term) 2

It is stated as: The product of the binomial sum and difference is equal to the square of the first term minus the square of the second term.
