Find the Derivative - d/dx x^2-9

Problem

d()/d(x)*(x2−9)

Solution

1. Identify the expression as a difference of two terms, allowing the use of the sum/difference rule for derivatives.

2. Apply the power rule to the first term, x2 which states that d(xn)/d(x)=n*x(n−1)

3. Differentiate the second term, 9 which is a constant. The derivative of any constant is 0

4. Combine the results of the individual derivatives to find the final expression.

Final Answer

(d(x2)−9)/d(x)=2*x
