Question

2x^2(x^3-x^2+1) +4x(x^4-2x^3+1)
cho mình xin lời giải chi tiết

 

Answer 1

`2x^2(x^3-x^2+1)+4x(x^4-2x^3+1)`

`=2x^5-2x^4+2x^2+4x^5-8x^4+4x`

`=6x^5-10x^4+2x^2+4x`

Answer 2

\(2x^2\left(x^3-x^2+1\right)+4x\left(x^4-2x^3+1\right)=2x^5-2x^4+2x^2+4x^5-8x^4+4x=\left(2x^5+4x^5\right)+\left(-2x^4-8x^4\right)+2x^2+4x=6x^5-10x^4+2x^2+4x\)
