    a^3 - b^3 = (a - b) * (a² + ab + b²) a = 2x and b = -3 <=> (2x)^3 - (-3)^3 = (2x - (-3)) * ((2x)² + (2x * (-3)) + (-3)²) = (2x + 3) * (4x² - 6x + 9)

    So I can solve (2x + 3) * (4x² - 6x + 9)

    There is no solving it is just factoring it.

    You can't solve something unless it is an equation or an inequality
