Given:
The given function is:

To find:
The differentiation of the given function.
Solution:
Consider the given function,

It can be written as:




Differentiate with respect to x.


Therefore, the differentiation of the given function is
.
A^2 + 2AB + B^2 = (A + B)^2 ==>
16X^2 + 40X + 25 =
= (4X)^2 + 2*4*5X + 5^2 =
= (4X + 5)^2
