Don't understand ur question

Answer 2

There are two ways by which you can do it.

In first method you need to differentiate it as we differentiate product functions.

Suppose y= u.v.w

where u,v,w are functions of x. then its differentiations given as

y’ = u’.v.w + u.v’.w + u.v.w’

in second and most easiest but lengthiest method we first open the brackets and then differentiate.

First method;

y=(x+2)(x-1)(x+3)

y’= (1+0)(x-1)(x+3) + (x+2)(1–0)(x+3) + (x+2)(x-1)(1+0)

y’=(x-1)(x+3) + (x+2)(x+3) +(x+2)(x-1) ———(1)

Solving equation (1) will give you the answer.

Second method;

y=(x+2)(x-1)(x+3)

y=(x^2+x-2)(x+3)

y= (x^3 + 4x^2 +x -6)——-(2)

Differentiating equation (2) will give you the answer.

Hope u will get it
