kipiarov [429]

Step-by-step explanation:

All of these terms have a common factor of 2, and when we take that out we get 2(x² + x - 6). To factor the polynomial in the parentheses, we have to find 2 numbers with a product of -6 and a sum of 1, and these are 3 and -2. Therefore, the final answer is 2(x + 3)(x - 2).
