What are the real and complex solutions of the polynomial equation x^3-216=0

Step-by-step explanation:

Factor the equation using formula for difference of the cubes:

then

1. The equation has real solution

2. The equation has negative discriminant then it has two complex solutions

step-by-step explanation:

3024 rhe base is what up in worry about

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.
