sort of like the last one
lets group them together
OpenStudy (31356):
OK
OpenStudy (31356):
You receive the medal already. ;)
OpenStudy (anonymous):
\[(2e^2-5e)+(7e-3e^2)\]
\[2e^2-3e^2-5e+7e\]
OpenStudy (31356):
Ok

1e^2-2e?
OpenStudy (anonymous):
now the like terms are together (terms with same exponent) so your final job is to compute
\[2e^2-3e^2\] and \[-5e+7e\]
OpenStudy (anonymous):
careful with your signs there
OpenStudy (31356):
Is it wrong?
OpenStudy (anonymous):
yes
what is \(-5+7\) or if you prefer \(7-5\) ?

-2 or 2
OpenStudy (anonymous):
lol no such number as "-2 or 2"
really i bet you know what \(7-5\) is
OpenStudy (31356):
2
OpenStudy (anonymous):
k good
and so \(-5e+7e=2e\) right?
OpenStudy (31356):
yes

now how about \(2e^2-3e^2\) which is really a matter of computing \(2-3\)
OpenStudy (31356):
-1e^2?
OpenStudy (anonymous):
yes!
OpenStudy (anonymous):
although it would make your teacher happier if you just wrote \(-e^2\) and omitted the unnecessary \(1\)
OpenStudy (31356):
-1e^2+2 for the answer right?
