Rewrite the following differences of squares as a product of two integers. (a). 81 − 1 (b). 400 − 121

(a) 10×8

(b) 31×9

Step-by-step explanation:

We have given that

(a) 81 - 1

We have to write this in form of product of two integers

We know the algebraic equation

As 81 -1 can be written as

So

(b) We have given 400 - 121

We have to write this in form of product of two integers

We know the algebraic equation

As 81 -1 can be written as

So
