$derivdef\left(y\left(x-3\right)+3\left(x-3\right)\right)$
Learn how to solve problems step by step online. Find the derivative of (y+3)(x-3) using the definition. Multiply the single term x-3 by each term of the polynomial \left(y+3\right). Multiply the single term y by each term of the polynomial \left(x-3\right). Multiply the single term 3 by each term of the polynomial \left(x-3\right). Find the derivative of xy-3y+3x-9 using the definition. Apply the definition of the derivative: \displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}. The function f(x) is the function we want to differentiate, which is xy-3y+3x-9. Substituting f(x+h) and f(x) on the limit, we get.
