Answer 1

Respuesta:

Explicación paso a paso:

• 2x – 5x + 9x =

– 3x + 9x =

6x

--------------------------------------------

• 2x + 7x + x – 8x =

9x – 7x =

2x

--------------------------------------------

• 5xy – 3x + 4xy =

9xy – 3x =

3x (9y – 1)

--------------------------------------------

• 9z + 8zy² – 5z + zy² – 15xy² =

4z + 9zy² – 15xy²

--------------------------------------------

• x + 3xy – 6x – 2x + 8xy + y – 2xy =

– 7x + 9xy =

x (–7 + 9y)

--------------------------------------------

• 8n – 4mn + 4n – 3mn + 5m =

12n – 7mn + 5m

--------------------------------------------

• 24m²n – 2mn – 12m²n – m³ =

12m²n  – 2mn – m³ =

m (12mn – 2n – m²)
