(4x³+ 13x − 7) − (6x²<span>+ 9x + 2) Remember that if they don't have the same exponents/bases (x</span>²,x³, etc.), then they cannot be grouped together.
This means that 4x³ and 6x² will be left alone because there are no other x² or x³ in the expression.
So first thing you do is distribute. Don't forget about that - in front of the second parentheses. (4x³+ 13x − 7) − (6x²+ 9x + 2) (4x³ + 13x − 7) + (−6x² - 9x - 2) 4x³ - 6x² + (13x - 7) + (-9x - 2) 4x³ - 6x² + 4x (- 7) + (- 2) 4x³ - 6x² + 4x - 9
So the answer is: C. <span>4x3− 6x2+ 4x − 9</span>
