    Simple algebra question

    My math is rusty because Im not sure how to get this answer 3y^2-2x^3=C.
    I have y^2/2-x^3/3=C and im solving for C. I subtract the x fraction and have y^2/2-x^3/3=C But im guessing thats wrong. What steps would I need to get to the right answer?
    Thanks

    Re: Simple algebra question

    hey I assume ^ means to the power of..... Use ( ) to seperate things......


    Ex.
    y^2/2-x^3/3=C

    y to the power of 2,divided by 2,minus x to the power of 3 divided by 3 eqals C.......Is this correct or am I mistaken?

    Hmm....i'm guessing this has something to do with calculus / integration, and C is some constant.

    Because, if you have:
    y2/2-x3/3 = C

    and multiply it by six you get:
    3y2-2x3 = 6C

    which is the same as your 'answer', but with 6C instead of just C
    however, if this is integration, or if C is some unknown constant, then you can replace 6C with C, and you get the same as the answer

    3 unknowns, 1 equation, no can do.

    what're you talking about?
    he's not trying to solve the equation, but just trying to simplify it.
    sql_lall is right, if the equation is a result of integration.
