Form a polynomial whose real zeros and degree are given.
Zeros: -3, -1, 1, 4; degree: 4
Type a polynomial with integer coefficients and a leading coefficient of 1.
f(x) = .
(Simplify your answer.)

Step-by-step explanation:

Given that zeroes of a polynomial are

-3, -1, 1, 4

Degree of the polynomial is 4

Also leading coefficient is 1.

So we find easily the polynomial

Since polynomial is 0 at the given four points the polynomial is a product of

Since leading coefficient is given to be 1 we need not multiply an arbitrary constant a

so the required polynomial is

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.

saving = more money

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.
