One number is 26 more than another. Their product is -169.

Step-by-step explanation:

Here, according to the question,

let one number be x and another number be x +26 as given in question that the another number is more than 26.

And their product is given as -169.

now, as per the condition of question,

x × (x+26)= -169

or, x^2+26x= -169

or, x^2+26x+169=0

or, (x+13)^2=0

or, (x+13)=0 (root under 0= 0)

or, x=-13.

Therefore, thevalue of x is -13.

And the value of (x+26) is (-13+26)=13.

Checking, 13×-13=-169.

Therefore, the 2 numbers are -13 and 13.

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.
