Explicación paso a paso:

a. (3X³ + 2X² + 5X) + (5X³ + 7X² + 8X)=

=3x³+2x²+5x+5x³+7x²+8x

=(3x³+5x³)+(2x²+7x²)+(5x+8x)

=8x³+9x²+13x

b. (3a 5b 2 - 6a₃ + 9b) + (5X⁵b 2 + 7a³ - 4b)=

=30ab+−6a³+9b+10bx⁵+7a³+−4b

=(10bx⁵)+(−6a³+7a³)+(30ab)+(9b+−4b)

=10bx⁵+a³+30ab+5b

c. (X⁶ + 4X⁵ - 5X⁴ – 2X³ ) + (8X⁴ + 10X³ + 6X³ - 5)=

=x⁶+4x⁵+−5x⁴+−2x³+8x⁴+10x³+6x³+−5

=(x⁶)+(4x⁵)+(−5x⁴+8x⁴)+(−2x³+10x³+6x³)+(−5)

=x⁶+4x⁵+3x⁴+14x³+−5

d. (X³Y + 2X² + 5X) + (-6X³Y - 2X²– X + 1)=

=x³y+2x²+5x+−6x³y+−2x²+−x+1

=(x³y+−6x³y)+(2x²+−2x²)+(5x+−x)+(1)

=−5x³y+4x+1

e. (4X² - 5X + 8) + (- 8X² + 10)=

=4x²+−5x+8+−8x²+10

=(4x²+−8x²)+(−5x)+(8+10)

=−4x²+−5x+18

Listo cariño:)!!

Answer 2

Respuesta:

a. (3x³ + 2x² + 5x) + (5x³ + 7x² + 8x)=

3x³ + 2x² + 5x + 5x³ + 7x² + 8x

8x³ + 9x² + 13x

b. (3a⁵b² - 6a³ + 9b) + (5X5b² + 7a³ - 4b)=

3a⁵b² - 6a³ + 9b + 5X5b² + 7a³ - 4b

3a⁵b² + a³ - 5b + 5Xb²

Aparte de que sea: 5X5b² = 5a⁵b²

Será....

3a⁵b² + a³ - 5b + 5a⁵b²

8a⁵b² + a³ - 5b

c. (x⁶ + 4x⁵ - 5x⁴ – 2x³ ) + (8x⁴ + 10x³ + 6x³ - 5)=

x⁶ + 4x⁵ - 5x⁴ – 2x³ + 8x⁴ + 10x³ + 6x³ - 5

x⁶ + 4x⁵ + 3x⁴ + 14x³ - 5

d. (x³y + 2x² + 5x) + (-6x³y - 2x² – x + 1)=

x³y + 2x² + 5x + -6x³y - 2x² – x + 1

-5x³y + 4x + 1

e. (4x² - 5x + 8) + (- 8x² + 10)=

4x² - 5x + 8 - 8x² + 10

-4x² -5x + 18
