Introduction to Polynomials Key Facts

• 0

• -1

• 1

• -8

Write the polynomial so that the powers of x are in descending order:

-3x + 8x² - 11 + 9x³

• It is already in descending order.

• 9x³ + 8x² - 3x - 11

• 8x² + 9x³ -11 - 3x

• -11 - 3x + 8x² + 9x³

Write the polynomial so the powers of x are in descending order.

9x² + 5x + 27 + 2x³

• 27 + 5x + 9x² + 2x³

• 9x² + 5x + 2x³ + 27

• 9x² + 5x + 27 + 2x³

• 2x³ + 9x² + 5x + 27
