$a\left(a-b-3c\right)+b\left(a-b-3c\right)-c\left(a-b-3c\right)$
Learn how to solve special products problems step by step online. Solve the product (a+b-c)(a-b-3c). Multiply the single term a-b-3c by each term of the polynomial \left(a+b-c\right). Multiply the single term a by each term of the polynomial \left(a-b-3c\right). When multiplying two powers that have the same base (a), you can add the exponents. Multiply the single term b by each term of the polynomial \left(a-b-3c\right).
