Answer 1

Respuesta:

a)

$5 {x}^{3} + 3 {x}^{2} + 2x + 3 {x}^{4} + {x}^{2} - 2x + 1 \\ 3 {x}^{4} + 5 {x}^{3} + 4 {x}^{2} + 1$

b)

$3 {x}^{4} + 2 {x}^{2} + x - 2 + {x}^{4} - 3x + {x}^{2} \\ 4 {x}^{4} + 3 {x}^{2} - 2x - 2$

c)

${x}^{5} - 2 {x}^{4} + {x}^{3} - 4x + 3 + 6 {x}^{4} + 12x - 9 \\ {x}^{5} + 4 {x}^{4} + {x}^{3} + 8x - 6$

d)

$2 {x}^{5} + 5 {x}^{4} - {x}^{3} - 2 {x}^{2} + 4x + 3 - 10 {x}^{5} + 23 {x}^{3} - 6 {x}^{2} + 8 \\ - 8 {x}^{5} + 5 {x}^{4} + 20 {x}^{3} - 8 {x}^{2} + 4x + 11$

e)

$3 {x}^{5} + 6 {x}^{4} - x + 2 - {x}^{5} + 2 {x}^{4} \\ 2 {x}^{5} + 8 {x}^{4} - x + 2$

f)

$- 4x + 3 + 8x - 3 \\ 4x$
