# How can you use polynomial identities to multiply expressions ? 41 39

Hint:

### where a and b can be real number, variables or multiples of them.

We are asked to find on how you could use a polynomial identity to multiply the given expression.

## The correct answer is: 1599

### Step 1 of 2 :

The given expression is : 4139

It can be written as : (40 + 1)(40 - 1) which is same as the expression 4139.

Step 2 of 2 :

Now, apply the polynomial identity, to get the required answer:

Polynomial identities are used to reduce the time and space while you solve higher degree polynomial expressions.
