Which of the following best describes the relationship between (x + 1) and the polynomial -3x3 - 2x2 + 1? a. (x + 1) is a factor. b. it is impossible to tell whether (x + 1) is a factor. c. (x + 1) is not a factor.

The answer's A.

To explain, let's say x is -1, which is true if (x+1) is a factor for the polynomial -3x^3 - 2x^2 + 1

From here, if you were to plug in -1 wherever you saw the x, the polynomial equals to 0, which means that (x+1) is a factor of the polynomial.

(C) (x+1) is not a factor

Step-by-step explanation:

To show that x+1 is not a factor, in other words to show that the polynomial cannot be written as a product

it suffices to test that x=-1 is not a root of the original cubic:

which is hereby shown and the option (A) is out.

Option (B) is non-sense.

Option (C) is the correct answer.

b

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
