Find the Derivative - d/dx (x^2)/(x-11)

Problem

d()/d(x)(x2)/(x−11)

Solution

1. Identify the rule needed for differentiation. Since the expression is a fraction of two functions, apply the quotient rule: d()/d(x)u/v=(vd(u)/d(x)−ud(v)/d(x))/(v2)

2. Assign the numerator and denominator functions. Let u=x2 and v=x−11

3. Differentiate the individual components. The derivative of the numerator is d(x2)/d(x)=2*x and the derivative of the denominator is d(x−11)/d(x)=1

4. Substitute these values into the quotient rule formula.

((x−11)*(2*x)−(x2)*(1))/((x−11)2)

5. Distribute the terms in the numerator to simplify the expression.

(2*x2−22*x−x2)/((x−11)2)

6. Combine like terms in the numerator.

(x2−22*x)/((x−11)2)

Final Answer

d()/d(x)(x2)/(x−11)=(x2−22*x)/((x−11)2)
