\[3x^2=33x+24\]

OpenStudy (ladiesman217):

@ajprincess @nubeer @.Sam. can you help me please

OpenStudy (ajprincess):

\(3x^2=33x+24\) \(3x^2-33x+24=0\) 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

OpenStudy (ladiesman217):

ya

OpenStudy (anonymous):

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

OpenStudy (ajprincess):

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

OpenStudy (ajprincess):

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

OpenStudy (ladiesman217):

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

OpenStudy (ajprincess):

b=-33

OpenStudy (ladiesman217):

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

OpenStudy (ajprincess):

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

OpenStudy (ladiesman217):

i got\[\frac{ 11\pm \sqrt{153} }{ 2 }\]

OpenStudy (ajprincess):

ya right:)

OpenStudy (ajprincess):

good work:)

OpenStudy (ladiesman217):

thnx

OpenStudy (ajprincess):

welcome:)
