    Answer: 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.
