solve for the value of x: 6log (x^2+1)-x=0. please help me because I do not have any idea in this topic.

    6log(x^2+1)-x=0

    6 log(x^2 + 1) = x
    log(x^2 + 1) = x/6
    x^2 + 1 = 10^(x/6)
    wow ....

    try Wolfram, since there is no "nice" way to solve this

    It says: x = 0 or x = appr .416 or x = appr 13.63

    check:
    x = 0
    LS = 6log 1 - 0 = 0 = RS , OK

    x = .416
    LS = 6log(1.173056) - .416 = -.00008 , not bad

    x = 13.63
    LS = 6log(186.7769) - 13.63 = -.00206 , not bad

    all three answers work
