Answer 2

Respuesta:

Explicación paso a paso:

1) (3x +6 x3 +7) + (- 4x2 + 5 – 8x) +( - x3 + 4x2 – 6 ) =

-5x+5x³+6

2) (x5 + x – 9) + (3x4 – 7x2 + 6) + (3x3 – 4x + 5) =

x5-3x+2+3x4-7x²+3x³

3) ( x2 – 3xy + y2) +( 2y2 + 3xy – x2 ) +( x2 +10xy – 7y2 )=

x²+10xy-4y²

4) (m3 – n3 + 6m2n) +( - 4m2n + 5mn2 + n3 ) =

m³+2m²n-5mn²

5) (6 a2+10 a – 2) +(5 a – 4 +9 a3) +4 a3 – 6a=

6a²+9a-6+13a³
