Answer:
The correct answer is 11x² + 11x - 6
Step-by-step explanation:
The given expression is,
(4x² + 12x - 9) + (7x² - x + 3)
<u>Simplify the given expression</u>
(4x² + 12x - 9) + (7x² - x + 3) = 4x² + 12x - 9 + 7x² - x + 3
= 4x² + 7x² + 12x - x - 9 + 3
= 11x² + 11x - 6
Therefore the simplified form of given expression is 11x² + 11x - 6
