Question
Use polynomial identities to multiply the expressions ? 
Hint:
, where a and b can be real values, variables or multiples of both. We are asked to use polynomial identities to find the product of the expression.
The correct answer is: (3x2 - 4xy)(3x2 + 4xy) = 9x4 - 16x2y2.
Step 1 of 2:
The given expression is . It is of the form (a - b)(a + b) where 
Step 2 of 2:
Use the polynomial identity to find the product of the expression,
Thus, the product is 
.
Thus, the product is
.The multiplication of algebraic expressions is a method of multiplying two given expressions consisting of variables and constants.
