Which of the following equations are equivalent to \( a x^{2}+b x+c=0 \) ? Check all that apply. \[ \begin{array}{l} x^{2}+\frac{b}{a} x+\frac{c}{a}=0 \\ x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} \\ x=-b \pm \frac{\sqrt{b^{2}-4 a c}}{2 a} \\ \left(x+\frac{b}{2 a}\right)^{2}=\frac{b^{2}-4 a c}{4 a^{2}} \\ \left(x+\frac{b}{2 a}\right)^{2}=\frac{b^{2}-4 a c}{2 a} \\ a x^{2}+b x=-c \\ x^{2}+b x=-c \end{array} \] Question Help: Video \( \square \) Message instructor
