$a^2-\left(3b\right)^2$

Learn how to solve special products problems step by step online. Solve the product (a+3b)(a-3b). The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: (a+b)(a-b)=a^2-b^2.. The power of a product is equal to the product of it's factors raised to the same power. Calculate the power 3^2.
