    5x^2 - 20 can be factored as 5(x^2-4) = 5(x+2)(x-2)

    (x+2) can be cancelled out and 3x^2 can also be cancelled out so you are left with \\[\frac{5x-10}{10x}\]

    3x^2 can be canceled because you simplified it with 30x^3?

    I am assuming moneybird was correct and further simplified the final answer.

    As shown I removed the common factor and placed it outside parenthesis. then divided numerator and denominator by the 5. getting the final answer

    (3x^2/x+2)/(5x^2-20/30x^3) (3x^2/x+2) * ( 30x^3/ (5x^2-20) = 90 x^3/ 5 ( x^3 - 8) = 18 x^3/ ( x^3 - 8)
