    d. 4x^2-20x-25

    Step-by-step explanation:

    So, we have to multiply (2x-5) by itself. That gives:

    (2x-5) (2x-5) = 2x (2x-5) - 5 (2x-5) = 4x² - 10x - 10x + 25

    so, the correct answer is 4x² - 20x + 25

    It's just important to multiply each component carefully by using the distributive property.
