yepp i got that

Answer 24

2nd step is plug in the values so .. \[\frac{ -3\pm \sqrt{3^{2}-4\times4\times}(-8) }{ 2\times4 }\]

Answer 25

step 3 simplify expression under square root so ..
\[\frac{ -3\pm \sqrt{137} }{ 8 }\]

Answer 26

ok

Answer 27

thas the answer

Answer 28

no step 4 solve for x

Answer 29

ok

Answer 30

\[\frac{ -3+\sqrt{137} }{ 8 }=-\frac{ 3 }{ 8 }+\frac{ 1 }{ 8 }\sqrt{137}\]

Answer 31

^ x1

Answer 32

\[\frac{ -3-\sqrt{137} }{ 8 }=-\frac{ 3 }{ 8 }-\frac{ 1 }{ 8 }\sqrt{137}\]

Answer 33

^ x2

Answer 34
