    A = 4x⁴ - 38x² + 81

    Step-by-step explanation:

    The formula for the area of a square is side X side, or side squared, or A = s².

    Substitute the equation of a side into the formula.

    A = s²

    A = (2x² - 9) ²

    A = (2x² - 9) (2x² - 9) <=distribute over brackets

    A = 4x⁴ - 18x² - 18x² + 81 < = collect the like terms - 18x² and - 18x²

    A = 4x⁴ - 38x² + 81 < = final equation for area
