Differentiation of ( (x^2-5 x+8 ) (x^3+7 x+9 ) ) can be done by

Options

  1. AOnly by using product rule
  2. BOnly by obtaining a single polynomial, expanding it
  3. COnly by using logarithmic differentiation
  4. DAll of the options are correct

Correct answer

D. All of the options are correct

Step-by-step solution

As given function contains two factors we can apply product rule or we can multiply factors to get a single polynomial. Another way is to take logarithm and then differentiate.
