$derivdef\left(x\left(x+3\right)+x+3\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of (x+1)(x+3) using the definition. Multiply the single term x+3 by each term of the polynomial \left(x+1\right). Multiply the single term x by each term of the polynomial \left(x+3\right). When multiplying two powers that have the same base (x), you can add the exponents. Combining like terms 3x and x.
