Answer:
y = x^2 -6x -27
Step-by-step explanation:
When "a" is a root, (x-a) is a factor. The minimum polynomial with the listed roots will be ...
y = (x -9)(x +3)
y = x^2 -6x -27
<h3>Your answer would be C, or 
.</h3>
To factor this polynomial, take out a greatest common factor from all of the terms.
In this case, we can look at the coefficients of x and x itself separately, and then combine them at the end.
The coefficients of x are 3, -12, and 27.
The greatest common factor between these numbers would be 3, as each of those numbers are divisible by 3.
Now, looking at x, you see .
The greatest common factor between these numbers would just be x, as all of these are divisible by x.
Now, combine these factors. 3 and x are the two greatest common factors, and putting them together, you get 3x.
To finish factoring this, factor out 3x from the polynomial, and combine them.
The polynomial is . To factor 3x out of them, divide each term by 3x.
That would be your answer, C.
Good luck!
