b) 15y3 + 5y2 + y – 1 – 8y3 + 8y2 + 5y + 3
c) (x2 + 3x – 1) + (9x2– 12x – 9)
d) (4x3– 4x2 + 2x + 1) – (2x3– 3x2 + x + 2)

pfvvv

Answer 1

a) 4x²-3x+3-2x²-3+7x = 2x²+4x

b) 15y³+5y²+y-1-8y³+8y²+5y+3 = 7y³+13y²+6y+2

c) (x²+3x-1) + (9x²-12x-9) = 10x²-9x-10

d) (4x³-4x²+2x+1) – (2x³-3x²+x+2) =

4x³-2x³-4x²+3x²+2x-x+1-2

2x³-x²+x-1
