Answer 1

1)

(-3x²+2x⁴-8-x³+1/2 x) + (-5x⁴-10+3x+7x³)=

2x⁴-5x⁴-x³+7x³-3x²+1/2x+3x-8-10= -3x⁴+6x³-3x²+7/2x-18

2)

(-3x²+5x-4) + (4x³-5x²+2x+1)= 4x³-3x²-5x²+5x+2x-4+1= 4x³-8x²+7x-3

3)

(9+5x³-4x²+x) + (4x²-3-2x)= 5x³-4x²+4x²+x-2x+9-3= 5x³-x+6

4)

(4x³+5) + (-2x+x²)= 4x³+x²-2x+5

5)

(-3xy²+4-7x²y²-6x²y-5xy) + (8xy-2xy²+10+4x³y)= 4x³y-7x²y²-6x²y-3xy²-2xy²-5xy+8xy+4+10

4x³y-7x²y²-6x²y-5xy²+3xy+14
