log x (x+2)=2

  • math -

    is that log(x(x+2))=2 or is it (log(x)) times (X+2)=2?

  • math -

    (logx)(x+2)=2

  • math -

    more than likely you want

    logx (x+2) = 2
    then
    x^2 = x+2
    x^2-x-2 = 0
    (x-2)(x+1) = 0
    x = 2 or x = -1
    but the base of any log has to be positive so,
    x = 2
