Correct Answer
Option D
Explanation
To solve the problem and verify why Option 4 is the correct answer, we need to perform the algebraic operations as described in the question. First, let's calculate \( A + B + C \): - \( A = 3x^2 - 8x + 11 \) - \( B = -2x^2 + 12x \) - \( C = -4x^2 + 7 \) Adding these together: \[ A + B + CтАжRead More
