Find the Derivative - d/d@VAR f(x)=(x^3-3x^2+4)/(x^2)

Problem

d()/d(x)(x3−3*x2+4)/(x2)

Solution

1. Simplify the expression by dividing each term in the numerator by the denominator x2

ƒ(x)=(x3)/(x2)−(3*x2)/(x2)+4/(x2)

2. Rewrite the terms using exponent rules to make differentiation easier.

ƒ(x)=x−3+4*x(−2)

3. Apply the power rule, which states d(xn)/d(x)=n*x(n−1) to each term individually.

d(ƒ(x))/d(x)=d(x)/d(x)−d(3)/d(x)+(d(4)*x(−2))/d(x)

4. Calculate the derivative of each term.

d(ƒ(x))/d(x)=1−0+4*(−2)*x(−3)

5. Simplify the resulting expression and rewrite with positive exponents.

d(ƒ(x))/d(x)=1−8*x(−3)

d(ƒ(x))/d(x)=1−8/(x3)

6. Combine into a single fraction by finding a common denominator.

d(ƒ(x))/d(x)=(x3−8)/(x3)

Final Answer

d()/d(x)(x3−3*x2+4)/(x2)=(x3−8)/(x3)
