Question 118762

{{{3x^2 - 2x = 15x - 10}}}


{{{3x^2 -2x -15x + 10 = 0}}}


{{{3x^2 -17x + 10 = 0}}}


{{{x[1,2]=(-b +- sqrt (b^2 -4*a*c )) / (2*a)}}}


{{{x[1,2]=(-(-17) +- sqrt ((-17)^2 -4*3*10 )) / (2*3)}}}


{{{x[1,2]=(17 +- sqrt (289 - 120)) /6}}}


{{{x[1,2]=(17 +- sqrt (169)) /6}}}


{{{x[1,2]=(17 +- 13) /6}}}



{{{x[1]=(17 + 13) /6}}}


{{{x[1]=30/6}}}


{{{x[1]= 5}}}



{{{x[2]=(17 - 13) /6}}}


{{{x[2]= 4/6}}}


{{{x[2]= 2/3}}}
