    The values of a, b and c are.

    a = 2, b = - 3 and c = - 2

    None of the options are correct

    Step-by-step explanation:

    Given

    Quadratic equation: 0 = 2x² - 3x - 2

    Required: The value of a, b and c.

    The general format of a quadratic equation is

    ax² + bx + c = 0

    So, we start by re-writing the given quadratic equation to give.

    2x² - 3x - 2 = 0.

    Then we make comparisons base on the position of each unit element of the quadratic equation

    ax² = 2x²

    Divide both sides by x²

    a = 2

    bx = - 3x

    Divide both sides by x

    b = - 3

    And lastly

    c = - 2.

    Hence, the values of a, b and c are.

    a = 2, b = - 3 and c = - 2

    None of the options are correct.
