Quadratic equation is it?

  1. Jun 18, 2012 #1
    (x+3)(x-4)(x-2)(x+1) = 24
    Can we change it into a quadratic equation without multiplying the expressions under those brackets?

    No, this will be a quartic (4th degree in x) whichever way you play with it. You can easily see this because the only way for it to become a quadratic is if the LHS x4 and x3 coefficients are cancelled, which isn't going to happen since the RHS only has a constant.

    You should realize that 3 times 4 times 2 is equal to 24, so you definitely want to expand.
