He is incorrect because if a number is before a letter than the number is the coefficient. and the coefficient is always multiplied by the letter its next to. since f is being distributed to x (multiplied because of the parentheses) then fx=3x which means f = 3 which means 3x=3x
Answer:

Answer:
the answer would look like this:
Zeros 2, 3, 5
(x-2) (x-3) (x-5) = 0
(x^2 - 2x- 3x +6) (x - 5) =0
(x^2 – 5x + 6) (x - 5) = 0
x^2 (x -5) - 5x (x - 5) + 6 (x - 5)=0
x^3 - 5x^2 -5x^2 + 25x + 6x - 30 = 0
The cubic polynomial function would be this one:
x^3 -10 x^2 + 31x - 30 = 0
Step-by-step explanation:
<span>Real
numbers are closee under addition.
Explanation: that means that the addtion of two real numbers is always a real number.
Integers are not closed under division.
Explanaton: that means that when you dived an integer number by another integer number the result may be a non integer number.
Irrational numbers are not closed under multiplication.
Explanation: that means that the multiplication of two irrational numbers may result in a rational number.
Rational numbers
are closed under subtraction.
