where x = the square of 2
OpenStudy (anonymous):
x+(3x) 2 +x over 2
OpenStudy (anonymous):
what does X equal...you just said two different things D:
OpenStudy (anonymous):
x = the square of 2\[\sqrt{2}\]
OpenStudy (anonymous):
the sqrt ok
\[\frac{ x + 3x^2 + x }{ 2 }\]
that it?

yes!! i couldn't find how to make it do that
OpenStudy (anonymous):
sigh,, only there are parenthesis around the 3x^2
OpenStudy (anonymous):
equation button, anyway put in sqrt of 2 everywhere u see x
so
\[\frac{ \sqrt{2} + 3\sqrt{2}^2 +\sqrt{2} }{ 2 }\]
OpenStudy (anonymous):
\[(3\sqrt{2}^2) or (3\sqrt{2})^2\]
OpenStudy (anonymous):
yes i got that far

*\[x+ (3 \sqrt{2})^{2} +x\]
OpenStudy (anonymous):
oh ok that's easy
\[\frac{ \sqrt{2} + (3\sqrt{2})^2 +\sqrt{2} }{ 2 }\]
OpenStudy (anonymous):
not easy to me :'(
OpenStudy (anonymous):
but that is the correct way to write it
OpenStudy (anonymous):
well what's sqrt of 2 plus sqrt of 2

the square root of 4
OpenStudy (anonymous):
which is! lol
OpenStudy (anonymous):
2
OpenStudy (anonymous):

well with that sqrt of 2 it's squared so the square root and the square cancel each other leaving us 2
OpenStudy (anonymous):
got it!!!! thank you!!!!
OpenStudy (anonymous):
\[\frac{ 2 + 9 + 2 }{ 2 }\]
OpenStudy (anonymous):
tyty!!! this makes sense now!!!
OpenStudy (anonymous):
