Question

# Use polynomial identities to multiply each expression

Hint:

### . Here a and b can be real values, variables or multiples of both. We are asked to use polynomial identities to multiply each expression.

## The correct answer is: (a + b)(a + b)

### Step 1 of 2:

The given expression is .

Here, the value of .

Step 2 of 2:

Substitute the values in the expansion to get the product. Thus, we have:

Hence, the product is:

Hence, the product is:

Any expression of the form (a + b)2 can be expanded using the identity rather than using the conventional and time taking method of multiplying them, (a + b)(a + b)
