you need to use quadratic formula \[\huge\rm x =\frac{ -b \pm \sqrt{b^2 -4ac} }{ 2a }\] a ,b,and c values are \[\large\rm Ax^2+Bx+C=0\] a=leading coefficient b= middle term c= constant term

remember c is constant term and a is leading coefficient \[\huge\rm \color{reD}{A}x^2+\color{blue}{B}x+\color{salmon}{C}=0\] \[\huge\rm \color{ReD}{1}x^2+\color{blue}{2}x+\color{salmon}{4}=0\]
