Question

What is the answer of this question​

Answer 1

Answer:

The answer is =2x^5-4x^3/x^4-2x^2+1

Step-by-step explanation:

D/dx(x^4/x^2+1)

By using quotient rule,

D/dx(x^4).(x^2-1)-d/dx(x^2-1).x^4

/(x^2-1)^2

=4x^3.(x^2-1)-(2x-0).x^4/x^4+1^2-2x^2

=4x^5-4x^3-2x^5/x^4+1-2x^2

=2x^5-4x^3/x^4-2x^2+1

Hope it helps mark me as brainiest.
