Concept
The cells are \(3x^2\), (6x), (-5x), and (-10), whose sum is \(3x^2+x-10\). In exams include the sign of every cell.
Why this answer is correct
The correct answer is A. \(3x^2+x-10\) / signed sum. The cells are \(3x^2\), (6x), (-5x), and (-10), whose sum is \(3x^2+x-10\). In exams include the sign of every cell.
