simplify -3b4+b3-(B3+B4-3)

OpenStudy (pfenn1):

I am not sure how to read that expression. Is it\[-3b ^{4}+b ^{3}-(b ^{3}+b ^{4}-3)\]

OpenStudy (anonymous):

yes

OpenStudy (pfenn1):

collect like terms\[-3b ^{4}-b ^{4}+b ^{3}-b ^{3}+3-?\]

OpenStudy (pfenn1):

*=?

OpenStudy (anonymous):

is that the answer

OpenStudy (pfenn1):

no, you have to simplify the terms what is\[-3b ^{4}-b ^{4}= ?\]

OpenStudy (anonymous):

-3

OpenStudy (pfenn1):

what is\[b ^{3}-b ^{3}= ?\]

OpenStudy (anonymous):

0

OpenStudy (pfenn1):

no, not -3. \[-3b ^{4}-b ^{4}=(-3-1)b ^{4}=-4b ^{4}\] and yes, the other term =0 so what does the expression simplify to?

OpenStudy (anonymous):

-4b4

OpenStudy (pfenn1):

right but you forgot that last term, the +3 at the end \[4b ^{4}+3\]

OpenStudy (pfenn1):

Sorry, I meant \[-4b ^{4}+3\]
