Question

a) 3x²+2x²-x²-x³+1/3x²-x+x²-1/4x³

b) x a la quinta +x+5x a la quinta -1/3x2+3x-2/3x²+5x

Answer 1

A) 3x²+2x²-x²-x³+1/3x²-x+x²-1/4x³=
(3x²+2x²-x²+1/3x²+x²) + (-x³-1/4x³) - x=
16/3x² - 5/4x³ - x=
- 5/4x³ + 16/3x²  - x
b) x a la quinta +x+5x a la quinta -1/3x2+3x-2/3x²+5x=
(x a la quinta +5x a la quinta) + (-1/3x2-2/3x²)+ (x +3x+5x)=
(6x a la quinta) - 1x² + 9x=
