Answer: 12x^2 +5x + 7

Step-by-step explanation:

You just need to combine like terms. you can combine 8x^2 and 4x^2 since they both have the same x^2 value. There is nothing to combine 5x with, so it remains 5x. Finally, you add the two integers, 4 and 3. This gives you the final answer, which is a quadratic equation.
