I'm quite lost so I'm unsure.

OpenStudy (anonymous):

ugh, dan wont reply

OpenStudy (anonymous):

Which ones are you solving?

OpenStudy (anonymous):

the first one i posted

OpenStudy (anonymous):

quadratic formula

OpenStudy (anonymous):

\[x= \frac{ -b +-\sqrt{b^2-4ac} }{ 2a }\]

OpenStudy (anonymous):

i did then i got the second pic

OpenStudy (anonymous):

and dan told me to simplify and i got the 3rd pic

OpenStudy (anonymous):

\[x=\frac{ -3+-\sqrt{3^2 - 4(2)(5)} }{ 2(2) }\]

OpenStudy (anonymous):

simplify

OpenStudy (anonymous):

is it this

OpenStudy (anonymous):

?

OpenStudy (anonymous):

\[x=\frac{ -3+-i \sqrt{31} }{ 4 }\]

OpenStudy (anonymous):

thats the answer? to the question

OpenStudy (anonymous):

no clue, can you simplify more?

OpenStudy (anonymous):

dont think so

OpenStudy (anonymous):

It seems right to me. although you can still simplify it more your answer space only ask for one so I guess that works.
