Best ResponseYou've already chosen the best response.0A quadratic equation is ALWAYS "Ax^2 + Bx + C = y" To use the quadratic formula, you will want to substitute 0 for y, which has already been done. Can you figure out what A, B, and C are in the quadratic equation you have?

Best ResponseYou've already chosen the best response.0So now we just substitute in 6 for a, 12 for b, and 5 for c then work out the equation

Best ResponseYou've already chosen the best response.0I got down to \[x= \frac{ 12\pm \sqrt{24} }{ 12 }\] now what do I do?

Best ResponseYou've already chosen the best response.0so where do I go from \[x= \frac{ 12 \pm 2\sqrt{6} }{ 12 }\]

Best ResponseYou've already chosen the best response.2You simplify it and divide by 2 because that is what they share in common
