Simplify

(2x^{2} - 5x + 3) - (-x^{2} + 4x - 5)

3x^2 - 9x + 8

Step-by-step explanation:

To simplify:

The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)

After distributing the -1, the equation becomes:

The like-terms are:

Combine the like-terms:

Substitute the simplified like-terms into the expression, in descending order:

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.

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
