Question

x(a-1)+m(a-1)-(a-1) una ayudita porfa​

Answer 1

Vamos a simplificar paso a paso.

x(a−1)+m(a−1)−(a−1)

Distribuir el signo negativo:

=x(a−1)+m(a−1)+−1(a−1)

=x(a−1)+m(a−1)+−1a+(−1)(−1)

=x(a−1)+m(a−1)+−a+1

Distribute:

=(x)(a)+(x)(−1)+(m)(a)+(m)(−1)+−a+1

=ax+−x+am+−m+−a+1

Solución:

=am+ax−a−m
