OpenStudy (shane_b):

Um...there's no need to do a quadratic here. The terms are all being added: Since that's the case, drop the parentheses and add up like terms: \[5x+5+3x-3=?\]

OpenStudy (anonymous):

Wait

OpenStudy (anonymous):

ok

OpenStudy (lgbasallote):

@learner26 you're right lol

OpenStudy (shane_b):

What did you get?

OpenStudy (anonymous):

OpenStudy (lgbasallote):

5x + 3 + 3x - 3 combine like terms

OpenStudy (lgbasallote):

the last term should not be 8. check again

OpenStudy (anonymous):

so 8x+8 is right

OpenStudy (anonymous):

8x+2

OpenStudy (lgbasallote):

OpenStudy (anonymous):

8x

OpenStudy (anonymous):

so 8x+8 is right

OpenStudy (lgbasallote):

OpenStudy (lgbasallote):

5x + 3 + 3x - 3 combine like terms 5x + 3x + 3 - 3

OpenStudy (lgbasallote):

OpenStudy (anonymous):

8x+2 is then right

OpenStudy (lgbasallote):

OpenStudy (anonymous):

0

OpenStudy (lgbasallote):

so what's 5x + 3x + 3 - 3

OpenStudy (anonymous):

8x-2

OpenStudy (lgbasallote):

what's 3 -3

OpenStudy (anonymous):

0

OpenStudy (lgbasallote):
