write this in algebraic expression;

the product of the sum and difference of numbers a and b​

Sagot :

(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.
