Which are real zeroes of this function? x3 + 2x2 – 9x – 18
a. 1, 2, 3
b. 3, -3, 2
c. 2, 3, -6
d. 1, -1, 18
e. -2, 3, -3

The answer is:

E. -2, 3, -3

To find the zeroes of the function, we just need to evaluate the given values and check if the function/expression tends to 0.

We are given the function

Now, to find the zeroes, we need to substitute the values, so, substituting the values of the option E, we have:

First value, -2:

Second value, 3:

Third value, -3:

Hence, we have that evaluating the values of the option E, the function tends to 0.

So, the correct option is: E. -2, 3, -3

Have a nice day!

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

thats not a system of equations, that is a solution
