If f(–5) = 0, what are all the factors of the function f(x)= x^3-19x+30? use the remainder theorem.

- (x-2)(x+5)(x-3)
- (x+2)(x-5)(x+3)
- (x-2)(x+5)
- (x+2)(x-5)

It's A in other words.

Step-by-step explanation:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
