Thank you for the opportunity to help you with your question!

3x^2-4x-5=0

d= 16-4*3*-5 = 16+60 = 76

x= (-(-4) +- sqrt 76)/2*3

  = (4 +- 2 sqrt19)/6

  = (2+- sqrt19)/3

   = (2+ sqrt 19)/3,  (2- sqrt 19)/3

Please let me know if you need any clarification. I'm always happy to answer your questions.
