What is the factored form of the polynomial? x2 − 12x + 27? (x + 4)(x + 3) (x − 4)(x + 3) (x + 9)(x + 3) (x − 9)(x − 3)

(x − 9)(x − 3)

Step-by-step explanation:

You can solve this problem finding the roots of the equation, by the bhaskara formula.

Explanation of the bhaskara formula:

Given a second order polynomial expressed by the following equation:

.

This polynomial has roots such that , given by the following formulas:

For , a = 1, b = -12, c = 27, so:

So, the factored form of the polynomial is (x-9)(x-3)

answer: d. $20
