Answer 1

Respuesta:

a. $3x^{3} - 3x + 2x - 2 = (3x^{2} - 3x ) + ( - 3x^{2} + 3x^{3} + 5x - 2)$

b. $3a^{2} - 7b^{2}x + 3ax - 7ab^{2} = (3 a^{2} + 3ax)-( 7b^{2}x + 7 ab^{2} )$

c. $4a^{3}x-4a^{2} b+3bm-3amx=(4a^{3}x-3amx)+(-4a^{2} b+3bm)$

d.$n^{2}x-5a^{2} y^{2} - n^{2} y^{2} +5a^{2}x = (n^{2}x- n^{2} y^{2})+(-5a^{2} y^{2}+5a^{2}x)$
