What would be the list of possible
rational numbers for f(x)?
x3 + 11x2 + 15x – 27 = 0

x=−3,−9,1

Step-by-step explanation:

x3 + 11x2 + 15x – 27 = 0

(factor using polynomial division)

(x^2+12x+27)(x−1)=0

(factor)

(x+3)(x+9)(x−1)=0

(solve for x)

x=−3,−9,1

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.
