Answer 2

Respuesta:

Punto 3)

a. 5x²-7x-8 +(-3x-9)

= 5x²-7x-8-3x-9

= 5x²-10x-17

b. 4a²+2ab+5b +(6a²-7ab)

= 4a²+2ab+5b +6a²-7ab

= 10a²-5ab+5b

c. (15mn² +6m²n -9m) +(-13m²n -2m +3)

= 15mn² +6m²n -9m -13m²n -2m +3

= 15mn² -7m²n -11m +3

d. m³/2 - 2m²/3 +(-2m³ /5 +m²/6 )

= m³/2 - 2m²/3 -2m³/5 +m²/6

= 3m³/10 -9m²/18

Punto 4

a. (6x²-3x -7) -(8x²+7x+4)

= 6x²-3x -7 -8x²-7x-4

= -2x² -10x -11

b. (24a²b -6ab -5) -(-7a²b -5ab -8)

= 24a²b -6ab -5 +7a²b +5ab +8

= 31a²b -ab +3

c. (3mn -6m²n² +2m²n³) -(24m²n² - 10m²n³)

= 3mn -6m²n² +2m²n³ -24m²n² +10m²n³

= 3mn -30m²n² +12m²n³

d. (9x -7y +9z) -( 3z -4y +2x)

= 9x -7y +9z -3z +4y -2x

= 13x -3y +6z

e. (-6ab² +8a²b) - (2ab/5 -4a²b/3 )

= -6ab² +8a²b - 2ab/5 +4a²b/3

= -6ab² +28a²b/3 - 2ab/5
