Explanation:

The given question is incomplete: find the complete question in the attachment.

- In this question, problem was set up correctly in the box.

- There is a mistake in the second row of the box.

It should be x | -2x³ | x² | -5x

- Further calculations should be,

-2x³ + x² - 5x + 6x² - 3x + 15

= -2x³ + (x² + 6x²) + (-5x - 3x) + 15

= -2x³ + 7x² - 8x + 15
