c) (4x³-4x²+2x+1) - (2x²-3x²+x+2)

Answer 1

a) x³-x²+7x²+10x³+4      
    x²(x-1+7+10x)+4

b)4a²b-3b²-6b²-2a²b-1  
   b(4a²-3b-6b-2a²)-1

c)(4x³-4x²+2x+1) - (2x²-3x²+x+2)
   [2x(2x²-2x+1)+1] - [x(2x-3x+1)+2)

Answer 2

a)x³-x²+7x²+10x³+4
   0          17x^{2}  + 4
b)4a²b-3b²-6b²-2a²b-1
2a^{2} b - 9b^{2}    -1
c) (4x³-4x²+2x+1) - (2x²-3x²+x+2)
(2x+1)- (-1x^{2} +x+2)
2x +3 - 1x^{2}+x
