x^2 + 3x + 4?

OpenStudy (anonymous):

how did you do that?

OpenStudy (anonymous):

because I learned that the factors of +4 have to sum to +3

OpenStudy (anonymous):

no it is not right!

OpenStudy (saifoo.khan):

HELL NO!

OpenStudy (saifoo.khan):

She is WRONG.

OpenStudy (anonymous):

that is how you factor \[x^2+4x+3\] not \[x^2+3x+4\]

OpenStudy (anonymous):

OpenStudy (saifoo.khan):

factors aren't possible.

OpenStudy (anonymous):

okay thanks

OpenStudy (anonymous):

\[\sqrt{-x}\] doesn't exist.
