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

Answer 1

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

Answer 2

answer or method?

Answer 3

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

Answer 4

same as my ans. thanks:)

Answer 5

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

Answer 6

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

Answer 7

ok

Answer 8

thank you:))

Answer 9

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

Answer 10

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

Answer 11

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