Hola me pueden ayudar estoy en un examen ;-;U
a. - 5xz + 4x – 3xz – 2x - 3xz =
b. -5x2y – 4xy – 5xy – 2x2y =
c. - 6x2 + 8x2 – 3y2 =
d. 3m2n3 – 6pq + 5 m2n3 – 4pq - 6 m2n3 + 8pq =
e. 2xy4 – 2x4y - 5xy4 =
f. 3ab + 5xy – 4ab – 3xy + 6ab =

Respuesta:
a. -5xz+4x-3xz-2x-3xz
= -5xz-3xz-3xz+4x-2x
= -5xz-3xz-3xz+2x
= -11xz+2x
b. - 5x²y-4xy-5xy-2x²y
= - 5x²y-2x²y-4xy-5xy
= - 7x²y-4xy-5xy
= - 7x²y-9xy
c. - 6x²+8x²-3y²
=2x²-3y²
d. 3m²n³-6pq+5m²n³-4pq-6m²n³+8pq
=3m²n³+5m²n³-6m²n³-6pq-4pq+8pq
=2m²n³-6pq-4pq+8pq
=2m²n³ -2pq
f. 3ab + 5xy – 4ab – 3xy + 6ab
=3ab-4ab+6ab+5xy-3xy
=5ab+5 xy-3xy
=5ab+2xy
Explicación paso a paso:
Espero haberte ayudado
