ok use the quadratic formula to find the solutions to 12x^2 - 31x + 7 = 0 tell me what those roots are

this will help you so much its a trick where you can solve any trinomial
anonymous
  • anonymous
basically you times the first term by last term which in ur case is 12 and 7
anonymous
  • anonymous
\[12 \times 7 = 84\]
anonymous
  • anonymous
now you need to find two factors of 84 which if multiply gives you 84 and when add gives you -31
anonymous
  • anonymous
so if you \[28 \times 3 = 84\]
anonymous
  • anonymous
now in order to get -31 these two number should be -28 and -3
anonymous
  • anonymous
\[(-28) + (-3)\]
anonymous
  • anonymous
now you equation will be \[12x ^{2} -3x -28x +7\]

now only thing you have to do is factor it , can u plz do that if u have trouble i ll help u
