Are u familiar with the quadratic formula? @CollinsWren.

thomaster (thomaster):

quadratic formula: \[x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]For the equation: \[3x^2-2x-3\]a=3, b=-2 and c=-3 You put a, b and c in the quadratic formula and put a plus on the place of the plusminus and solve it. Then you do it again but instead now you replace the + by a - and solve it again.
