Final answer:
To find the sum, combine like terms and simplify constants.
Step-by-step explanation:
To find the sum of the given expressions, you need to combine like terms. Start by adding the coefficients of the similar terms. In this case, you have:
Next, simplify the constant terms: 2 + 8 = 10.
Combining both results, you get the sum of the two expressions as 2x^2 - 7x + 10.
