Answer:
-3x³ + 44x² - 43x + 10
Step-by-step explanation:
![\left[\begin{array}{ccc}&-3x&2\\x^2&-3x^3&2x^2\\-14x&42x^2&-28x\\5&-15x&10\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26-3x%262%5C%5Cx%5E2%26-3x%5E3%262x%5E2%5C%5C-14x%2642x%5E2%26-28x%5C%5C5%26-15x%2610%5Cend%7Barray%7D%5Cright%5D)
= -3x³ + 2x² + 42x² - 28x - 15x + 10 = -3x³ + 44x² - 43x + 10
