[tex]8 x^{2} -24x[/tex] is not in equation form, and you gave no question as to what to find. If it says to factor, it can be [tex]8x(x-24)[/tex]. If it is asking to find x when [tex]8 x^{2} -24x[/tex] is equal to 0, then it is [tex]x=0,24[/tex]. I hope one of those answers the question you meant to ask.
