1.From the sum of 5x³+1 and 2x⁴-3x³-3x¹,Subtract x⁴-3x-2

2.Subtract the sum of 5x²+7x-1 and 3x²-5x+5 from 17x²-7x+11

3.Find the sum of 3 (x-2y) and -5 (x+y)

4.From the sum of 3x⁴-2x³+4 and x³-x²+5,subtract the sum of x⁴-9 and x³-2x+8

5.From the sum of(-9s-5) and (4s-10),subtract (s-8)

6.(2x-2y+3z)+(5x-6y-12z)

7.(5x-7y+9)+2x + 4y +4)

8.(4+8x-x²)+(2-2x +3x²)

9.(9+3x² -x)+(2x-3+8x²)

10.(x²+y²-z²)+(3z²-2x²-4y)+(4x²-5y²+z².
