Does not seem to be a general formula.
"Solve the following equation using the general formula for a quadratic equation", maybe that meant.

0=-3x%5E2%2Bx%2B3
Still not a general "formula".
3x%5E2-x-3=0

x=%281%2B-+sqrt%281%5E2%2B4%2A3%2A3%29%29%2F%282%2A3%29
x=%281%2B-+sqrt%2837%29%29%2F6

system%28x=%281-sqrt%2837%29%29%2F6%2Cor%2Cx=%281%2Bsqrt%2837%29%29%2F6%29
