Choose the expression that represents a cubic expression.
−7x + 14
7x2 − 5x + 6
8x3 − 7x2 − 6x + 5
9x4 + 8x3 − 6x2 − 2x + 11

8x³ - 7x² - 6x + 5

Step-by-step explanation:

8x³ - 7x² - 6x + 5 is a cubic expression.

The variable is x

The variable x has highest power as 3.

8x³ - 7x² - 6x + 5 is a polynomial.

-7x + 4 is a linear expression because highest power of the variable x is 1.

7x² - 5x + 6 is a quadratic expression because the highest power of the variable x is 2.

9x^4 + 8x^3 - 6x^2 - 2x + 11 is a polynomial with the highest power of the variable being 4.
