Solve for X using quadratic function
3y^2  2y = 5
I already subtracted the 5 to get 0 so my
A = 3^2
b= 2
c= 5
But im having trouble with the actual equation part which happens to be 2 + or  square root 2^2  4 * 9 * 5 over 2 * 9.

Best ResponseYou've already chosen the best response.1\[3y ^{2}2y5\] \[(2)\pm \sqrt{(2)^{2}4(3)(5)}/(2(3))\] your mistake is squaring the first coefficient. You do not need to. Recalculate from here, it should work out now.

Best ResponseYou've already chosen the best response.1\[(2\pm \sqrt{64})/6\] \[2\pm8/6\] =28=6/6=1 or 10/6=5/3
