$a\left(a-1\right)+3\left(a-1\right)$
Learn how to solve problems step by step online. Solve the product (a+3)(a-1). Multiply the single term a-1 by each term of the polynomial \left(a+3\right). Multiply the single term a by each term of the polynomial \left(a-1\right). When multiplying two powers that have the same base (a), you can add the exponents. Multiply the single term 3 by each term of the polynomial \left(a-1\right).
