    2. Which of the following expressions represents the product of 3 less than twice x and 2 more than the quantity 3 times x ?
    A. -6x2 + 25x + 6
    B. 6x2 + 5x + 6
    C. 6x2 - 5x + 6
    D. 6x2 - 5x - 6
    E. 6x2 - 13x - 6

    Solution:

    We can write 3 less than twice x as algebraic expression as (2x - 3)

    And 2 more than the quantity 3 times x as algebraic expression as (3x + 2)

    We have to find the product now

    (2x - 3)(3x + 2) ...
