Homework Help: Algebra: is it possible

  1. Dec 30, 2009 #1
    Hi everybody,

    I was wondering if it's possible to solve this equation:

    -42.2=-10.999x+-4.9x^2

    Now, I just wanna know if it's possible. I'm not asking for the answer.

    Greetings,

    Shawn

    P.S.
    A little push in the right direction is always welcome.

    Sure it's possible. Hint: Look up how to solve quadratic equations.

    -42.2=-10.999x+-4.9x^2

    add 42.2 to both sides

    0 = -4.9x2 - 10.999x + 42.2

    then use the quadratic equation to solve for x if that's what you're looking for.

    Make life simpler for yourself by adding 4.9x2 + 10.999x to both sides to get it in the form that Icystrike showed.
    Use the quadratic formula to solve this quadratic equation.
