Question

P(x) = 2x3 - 2x + x2 + 3x + 2

Q(x) = 4x3 - 3x2 - 3x + 4x - 3x3 + 4x2 + 1

a. Rút gọn P(x) , Q(x) .

Answer 1

\(\text{P(x)}=2x^3-2x+x^2+3x+2\)

\(P\left(x\right)=\left(-2x+3x\right)+2x^3+x^2+2\)

\(P\left(x\right)=x+2x^3+x^2+2\)

 

\(Q\left(x\right)=4x^3-3x^2-3x+4x-3x^3+4x^2+1\)

\(Q\left(x\right)=x^3+x^2+x+1\)

Answer 2

a)\(P\left(x\right)=2x^3-2x+x^2+3x+2\)

\(P\left(x\right)=2x^3+x^2+x+2\)

\(Q\left(x\right)=4x^3-3x^2-3x+4x-3x^3+4x^2+1\)

\(Q\left(x\right)=x^3+x^2+x+1\)

Answer 3

`a)``P(x)=2x^3-2x+x^2+3x+2`

`=2x^3+x^2+x+2`

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

`=x^3+x^2+x+1`
