Easy medal!

OpenStudy (anonymous):

\[\frac{ -4x+8 }{ -4 }\]

OpenStudy (anonymous):

and

jimthompson5910 (jim_thompson5910):

hint: -4x+8 = -4(x-2)

OpenStudy (anonymous):

\[\frac{ -4x-8 }{ -4 }\]

jimthompson5910 (jim_thompson5910):

-4x-8 = -4(x+2)

OpenStudy (anonymous):

common multiples!!!

jimthompson5910 (jim_thompson5910):

does that help rainbowtonic?

OpenStudy (anonymous):

so the answer is x-2 because -4 divided by -4 is 1 and 8 dived -4 is -2

OpenStudy (anonymous):

\[\frac{ -4x + 8 }{ -4 } = \frac{ -4(x - 2) }{ -4 }\]

OpenStudy (anonymous):

\[\frac{ -4x - 8 }{ -4 } = \frac{ -4(x + 2) }{ -4 }\]

OpenStudy (anonymous):

Can you do it from here? @rainbowtonic

OpenStudy (anonymous):

honestly no...

OpenStudy (anonymous):

okay, do you know why the numerator part (the top) got factored as it is?

OpenStudy (nincompoop):

where is my medal ? :)

OpenStudy (anonymous):

lol where is mine???

OpenStudy (anonymous):

okay we're gonna factor in that ive been awake for almost 26 hours now. 18 of that has been nonstop at my job. my brain im telling you is not functioning properly

OpenStudy (anonymous):

... okay? ...

OpenStudy (nincompoop):

she said easy medal… I didn't think she'd be this stingy about medals

OpenStudy (anonymous):

:l

OpenStudy (anonymous):

dont get snippy with me

jimthompson5910 (jim_thompson5910):

the idea is to factor out -4, then cancel like this \[\large \frac{ -4x+8 }{ -4 }\] \[\large \frac{ -4(x-2) }{ -4 }\] \[\large \frac{ \cancel{-4}(x-2) }{ \cancel{-4} }\] \[\large \frac{ 1(x-2) }{ 1 }\] \[\large \frac{ x-2 }{ 1 }\] \[\large x-2\] ------------------------------------- so \[\large \frac{ -4x+8 }{ -4 }\] simplifies to \[\large x-2\]

OpenStudy (anonymous):

so the second one would be x + 2?

OpenStudy (anonymous):

precisely
