Best ResponseYou've already chosen the best response.1there is a typo you forgot  and a at the denominator \[\huge\rm \frac{ \color{red}{ }b \pm \sqrt{b^2 4ac} }{ 2\color{reD}{a} }\] quadratic formula where abc values are \[\huge\rm Ax^2 +Bx+C=0\]

Best ResponseYou've already chosen the best response.3Well scratch that there are no multiplies of 30 that can add up or subtract to equal 9, so in this case we will use the quadratic formula.
