Question

Resolver las siguientes operaciones: a) 2x + 3x – 4x – 8x = b) 2m (2m2 + 6m – 9) = c) 3m + 4m – 5m – 6m = d) ( -2m2 + 4) (m2 + 4m – 7) =

Answer 1

Respuesta:

$a) 2x + 3x - 4x - 8x\\\\-7x\\\\\\b)2m(2m^2 + 6m - 9)\\\\4m^3 + 12m^2 - 18m\\\\\\c)3m + 4m - 5m - 6m\\\\7m - 11m\\\\-4m\\\\\\ d)(-2m^2 + 4)(m^2 + 4m - 7)\\\\-2m^3 - 8m^3 + 14m^2 + 4m^2 + 16m - 28\\\\-10m^3 + 18m^2 + 16m - 28$
