    It's 5x squared - 9x = 0

    Yeah. Your right Saifoo but then the positive one should be it....there should be a negative anser and a positive one.

    saifoo is right if it is 5x^2 the answer would be 9/5 and 0

    interesting. well can any of you two give me an equation and explain to me how you get the positive solution of it?

    factor out an x x(5x-9)=0

    Yeah!!!! A problem like that is what I have on my paper. Now...how do I get the positive solution of this?

  27. anonymous

    then set x=0 and 5x-9=0

    will we know that x=0 is one answer. then let's solve 5x-9=0. once we solve that we get 5x=9 then divide 5 by both sides we get 9/5

    No, it's 9/5. You factor out an x, and you use the zero product rule, setting x = 0 and (5x-9)=0, since, algebraically, you can do that. So, solving for x, you get x = 0 and x = 9/5
