    \(3x^2=33x+24\) \(3x^2-33x+24=0\) Use quadratic formula. \[x=\frac{ -b\pm\sqrt{b^2-4ac} }{ 2a }\] the values of a, b and c can be found by comparing the equation \(3x^2-33x+24=0\) with the general equation \(ax^2+bx+c=0\). Does that help? @ladiesman217

    **-24 dividing the entire equation by 3 would simplify calculations

    it is actually \(3x^2-33x-24=0\). am sorry abt the mistake

    ya. first factor out 3 and then divide by 3 both sides. After that use quadratic formula:)

    the equation i got was\[\frac{ -(-3)\sqrt{3^{2}-4(3)(-24)} }{ 2*3 }\]

    this is the correct equation right \[\frac{ -(-33)\sqrt{-33^{2}-4(3)(-24)} }{ 2*3 }\]

    it will be \[\frac{ -(-33)\sqrt{(-33)^2-4*3*(-24)} }{ 2*3}\]
