Question

F(x)=x⁴+5x²-4x+x⁵-x⁴-8x²+3+2x³+2

Answer 1

Thu gọn và sắp xếp phải k ạ?

`F(x)= (x^4-x^4)+(5x^2-8x^2)-4x+x^5+3+2x^3+2`

`F(x) = -3x^2-4x+x^5+3+2x^3+2`

`F(x)= x^5+2x^3-3x^2-4x+3+2`

Answer 2

\(F\left(x\right)=x^4+5x^2-4x+x^5-x^4-8x^2+3+2x^3+2\)

\(F\left(x\right)=x^5+\left(x^4-x^4\right)+2x^3+\left(5x^2-8x^2\right)-4x+\left(3+2\right)\)

\(F\left(x\right)=x^5+2x^3-3x^2-4x+5\)
