    24x^4 - 12x^2 or 12x^2 (2x^2-1)

    Step-by-step explanation:

    We are given the length and width of the rectangle:

    Length=l=4x^2

    and

    Width=w=6x^2-3

    The formula for the area of rectangle is:

    Area=length*width

    Area=l*w

    Putting the values of l and w into the formula:

    area = (4x^2) (6x^2-3)

    =24x^ (2+2) - 12x^2

    =24x^4 - 12x^2

    It can also be written as: taking 12x^2 as common:

    =12x^2 (2x^2-1)
