Question

Como efetuar as expressões:
2a-2m+2n=
4-8x-16y=
35ax-42ay=
5a²x-5a²m-10a²=
5a+20x+10=
55m+33n=
7am-7ax-7an=
2ax+2ay-2axy=

Answer 1

$2a-2m+2n= 2.(a-m+n) \\ \\ \\ 4-8x-16y= 4.(1-2x-4y) \\ \\ \\ 35ax-42ay= 7a.(5x-6y) \\ \\ \\ 5a^2x-5a^2m-10a^2= 5a^2.(x-m-2) \\ \\ \\ 5a+20x+10= 5.(a+4x+2) \\ \\ \\ 55m+33n= 11.(5m+3n) \\ \\ \\ 7am-7ax-7an= 7a.(m-x-n) \\ \\ \\ 2ax+2ay-2axy= 2a.(x+y-xy)$
