Question

differentiation of (45 x -2x^2 )( 24-2x)

Answer 1

• d(x)/d(y) = [45x - 2x^2] [-2] + [24 - 2x][-4x +45]

Solve this equation, you will get the answer :)

Answer 2

Answer:

$= >$

we know,

if y=uv then,

dy/dx= u X dv/dx + v X du/dx

therefore, Given eqn is,

y= (45 x -2x^2 )( 24-2x)

dy/dx=(45x-2x^2) x d/dx(24-2x)

+ (24-2x) x d/dx(45x-2x^2)

= (45x-2x^2) x (0-2)

+ (24-2x) x (45-4x)

= -2(45x-2x^2)+(24-2x) x (45-4x)
