Answer 1

Answer:

3x3+5x-2+x3-3x+1+4x3+2x

4x -1

Answer 2

$\mathtt{p(x) = 3x³+5x-2}$

$\mathtt{q(x) = x³-3x+1}$

$\mathtt{g(x) = 4x³+2x}$

$\mathtt{p(x)+q(x)-g(x)}$

$\mathtt{= (3x³+5x-2)+(x³-3x+1)-(4x³+2x)}$

$\mathtt{=3x³+5x-2+x³-3x+1-4x³-2x)}$

$\mathtt{= 3x³+x³-4x³+5x-3x-2x-2+1}$

$\mathtt{= -1}$
