Best ResponseYou've already chosen the best response.2Compare your quadratic equation with \(ax^2+bx+c=0\) find a,b,c then the two roots of x are: \(\huge{x=\frac{b \pm \sqrt{b^24ac}}{2a}}\)

Best ResponseYou've already chosen the best response.2no, 'a' is the coefficient of x^2 here u have 1x^2 so a=.... ?

Best ResponseYou've already chosen the best response.2remember that c=24 so \(b^24ac = 254(1)(24) = 25+96=...?\)
