Show that (4p^2-3q)^2+48p^2q =(4p^2+3q^2)​

Given:

The statement is

To prove:

The given statement.

Solution:

We have,

Now,

Using , we get

It can be rewritten as

Using , we get

Hence proved.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
