Answer 1

Respuesta:

1: 2x-5x+9x

=6x

2: 2x+7x+x-8x

=2x

3: 5xy-3x+4xy

=9xy-3x

=3x(3y-1)

4: 6x-8y-4y

=6x-12y

=6(x-2y)

5: 3y+5y-7y+x

=y+x

6: 8z+3xy-12z

=3xy-4z

7: 5m-9n+2n

=5m-7n

8: 10x+4y-y

=10x+3y

9: 6z-4z+2z

=4z

10: 3x-7y+5x+4y

=8x-3y

11: 6b-3b+8a-18b+a

=9a-15b

=3(3a-5b)

12: 9z+8zy²-5z+zy²-15xy²

=4z+9zy²-15xy²

=4z+3y²(3z-5x)

13: x+3xy-6x-2x+8xy+y-2xy

=9xy-7x+y

=x(9y-7)+y

14: 8n-4mn+4n-3mn+5m

=12n-7mn+5m

=n(12-7m)+5m

15: 24m²n-2mn-12m²n-m³

=12m²n-2mn-m³

=-m(m²-12mn+2n)
