5)Siendo : A = 5xy–4xy–2xy ; B = –xy + 3xy–4xy Hallar A–B?
5) Siendo : A = 5xy–4xy–2xy ; B = –xy + 3xy–4xy Hallar A–B.
En resumen
A = 5xy–4xy–2xy ; B = –xy + 3xy–4xy Hallar A–B entonces A = xy - 2xy y B = 2xy - 4xy A = - 1xy y B = - 2xy entonces A - B = a A - B = = - 1xy - - 2xy = - xy + 2xy A - B = xy.
Mejor respuesta
A = 5xy–4xy–2xy ;
B = –xy + 3xy–4xy
Hallar A–B
entonces
A = xy - 2xy y B = 2xy - 4xy
A = - 1xy y B = - 2xy
entonces A - B = a
A - B = = - 1xy - - 2xy = - xy + 2xy
A - B = xy.
