H²-16h +48=0
Find h. ​

12 or 4

Step-by-step explanation:

h square -h(12+4)+48

h square-12h-4h+48=0

h(h-12)-4(h-4)=0

h-12=0 equation 1

h-4=0 equation 2

from eqn 1

h-12=0

h=12

from eqn 2

h-4=0

h=4

Therefore value of h=12,4

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.
