Correct Answer
Option C
Explanation
To determine the sum of the coefficients of \(x^2\) and \(x\) in the expression \(A + B + C - D\), we first need to simplify the expression by combining like terms from each polynomial. Given: - \(A = -2x^2 + 12x\) - \(B = 11 - 8x + 3x^2\) - \(C = 17 - 4x^2\) - \(D = x^2 - x - 3\) Let's calculate \(A + B +тАжRead More
