Best ResponseYou've already chosen the best response.1nope :P well the quadratic formula states that \(\huge x=\frac{b \pm \sqrt{b^24ac}}{2a} \)

Best ResponseYou've already chosen the best response.1ok so if you have \(\huge ax^2+bx+c=0 \) substitute the values of a b and c into the formula and solve it.
