help☻ 4x−{3+[4−(x2−3x)+x3]−[3x2+(−3+4x)]+7x}

OpenStudy (anonymous):

\[4x−{3+[4−(x^2−3x)+x^3]−[3x^2+(−3+4x)]+7x}\]?

OpenStudy (anonymous):

answer or method?

OpenStudy (anonymous):

\[-x^3+4 x^2-2 x-10\]

OpenStudy (anonymous):

same as my ans. thanks:)

OpenStudy (anonymous):

can u show me ur solutions? Because I want to see if we have the same..

OpenStudy (anonymous):

i did it on paper, but i am sure if we got the same answer we did the same thing. work from inside out, remove parentheses etc

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

thank you:))

OpenStudy (anonymous):

\[4x−(3+[4−(x^2−3x)+x^3]−[3x^2+(−3+4x)]+7x)\] \[4x-(3+4-x^2+3x+x^3)-3x^2+3-4x-7x\] \[4x-3-4+x^2-3x-x^3-3x^2+3-4x-7x\] \[-x^3+(x^2-3x^2)+(4x-4x-7x)-3-4+3\] hmm maybe i made a mistake.

OpenStudy (anonymous):

no it is right. first thing i mean. can't keep track here too hard to write all out

OpenStudy (anonymous):

so the ans. is \[-x^3-2x^2-7x-2\]
