Find the Derivative - d/dx y=((x+2)x)/(x+1)

Problem

d()/d(x)((x+2)*x)/(x+1)

Solution

1. Expand the numerator to simplify the expression before differentiating.

y=(x2+2*x)/(x+1)

2. Identify the quotient rule formula for a function u/v which is (vd(u)/d(x)−ud(v)/d(x))/(v2)

u=x2+2*x

v=x+1

3. Differentiate the numerator u and the denominator v with respect to x

d(u)/d(x)=2*x+2

d(v)/d(x)=1

4. Apply the quotient rule by substituting the components into the formula.

d(y)/d(x)=((x+1)*(2*x+2)−(x2+2*x)*(1))/((x+1)2)

5. Simplify the numerator by distributing the terms.

d(y)/d(x)=(2*x2+2*x+2*x+2−x2−2*x)/((x+1)2)

6. Combine like terms in the numerator to reach the final simplified form.

d(y)/d(x)=(x2+2*x+2)/((x+1)2)

Final Answer

d()/d(x)((x+2)*x)/(x+1)=(x2+2*x+2)/((x+1)2)
