$a\left(a-3b\right)+3b\left(a-3b\right)$
Learn how to solve special products problems step by step online. Solve the product (a+3b)(a-3b). Multiply the single term a-3b by each term of the polynomial \left(a+3b\right). Multiply the single term a by each term of the polynomial \left(a-3b\right). Multiply the single term 3b by each term of the polynomial \left(a-3b\right). Cancel like terms -3ba and 3ab.
