Find the Derivative - d/dx (x^3-3x^2+4)/(x^2)

Problem

d()/d(x)(x^3−3*x^2+4)/(x^2)

Solution

1. Simplify the expression by dividing each term in the numerator by the denominator x^2 to avoid using the quotient rule.

(x^3−3*x^2+4)/(x^2)=(x^3)/(x^2)−(3*x^2)/(x^2)+4/(x^2)

2. Rewrite the terms using exponents to prepare for differentiation.

x−3+4*x^(−2)

3. Apply the power rule d(x^n)/d(x)=n*x^(n−1) to each individual term.

d(x)/d(x)−d(3)/d(x)+(d(4)*x^(−2))/d(x)

4. Calculate the derivative of each part.

1−0+4*(−2)*x^(−3)

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

1−8*x^(−3)

1−8/(x^3)

Final Answer

d()/d(x)(x^3−3*x^2+4)/(x^2)=1−8/(x^3)
