Complete the quare to solve the equation below x^2-10x-4=10

x1= -(square root of 39) + 5

x2=(square root of 39) + 5

Step-by-step explanation:

x^2-10x=10+4

x^2-10x+(10/2)^2=14+(10/2)^2

(x-10/2)^2=14+25

(x-5)^2=39

x1= - (square root of 39) + 5

x2= (square root of 39) + 5

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.
