Find the differential of the equation: x^2(2x+5)

First expand the equation, giving us 2x^3 + 5x^2Then you can differentiate the equation by multiplying the number at the front of x by its power.Only then, we need to subtract 1 from the power.This gives us 6x^2 + 10x

Integrate y= x^3+3x^2-4x-7 between x values 1 and 3


y = 4x/(x^2+5). a) Find dy/dx, writing your answer as a single fraction in its simplest form. b) Hence find the set of values of x for which dy/dx < 0


I don't understand differentiation. How does it work?


The curve C has the equation 4x^2 - y^3 - 4xy + 2y = 0 . The point P with coordinates (-2, 4) lies on C. Find the exact value of dy/dx at the point P.
