Answer 2

Hola Nidia0214p4emlm, 

- 2(3 + 5(- 2(3 + 5) + 6(- 5 + 1) + 3) + 2(3 - 1)) + 2
= - 2(3 + 5(- 2 x 8) + 6 x (- 4) + 3) + 2 x 2) + 2
= - 2(3 + 5 x (- 16 + (- 24) + 3) + 4) + 2
= - 2(3 + 5 x (- 16 - 24 + 3) + 4) + 2
= - 2(3 + 5 x (- 40 + 3) + 4) + 2
= - 2(3 + 5 x (- 37) + 4) + 2
= - 2(3 - 185 + 4) + 2
= - 2(7 - 185) + 2
= - 2 x (- 178) + 2
= 356 + 2
= 358
