Consider the perfect square trinomial identity:a^2+2ab+b^2=(a+b)^2

Step-by-step explanation:

x² + 10x + 25

a² +2ab + b² = (a + b)²

b² = 25

b = √25

b = 5

2ab = 2*x*5 = 10x

horizontal translation of 2 units in the positive x direction

vertical translation of 3 units in the positive y direction

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.
