what are the zeros of the polynomial function f(x)=x(x-4)(x+9)

a. 0,4,-9
b. 1,-4,9
c. 0-4,9
d. 1,4, -9

1. x = 0, 4, -9

2. x = 3, 3, -5

3. 2x^3 - 9x^2 + 7x + 6

4. x = -6, -8, -15

5. 2x^3+10x^2+12x

Factor out the common factor:

2x (x^2+5x+6 )

Factor what's left in parentheses:

2x (x + 2) (x + 3)

6. x = 0, 4, -9

Step-by-step explanation:

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

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.
