Answer 2

I'm pretty sure it is c
But help?

Answer 3

Thats correct

Answer 4

\[\huge~\rm~~x=\frac{ -b~\pm \sqrt{b^2-4ac} }{ 2a } \]
\[\huge~\rm~~x=\frac{ -(-16)~\pm \sqrt{(-16)^2-4(-2)(-44)} }{ 2(-2) } \]

there c:

Answer 8

\[x^2+8x+22=0\]
\[x^2+8x+16-16+22=0,x^2+8x+16=-6\]
\[\left( x+4 \right)^2=-6,x+4=\pm \sqrt{-6},x=-4\pm \sqrt{-6}\]
