    hey SHEvA9,
    It would be great help if you could tell us how exactly have you approached it... so that we know what exactly is your doubt.
    I am sure we can solve it together

    Cheers
    Thanks from topsquark

    Square both sides:
    \\9x^2-24x+16>4x^2+12+9\\5x^2-36x+7>0\\(5x-1)(x-7)>0\\x<\tfrac{1}{5}\text{ or }7<x~.
