a) 2x2y3z + 3x2y3z = 5x2y3z
b) 2x3 − 5x3 = −3x3
c) 3x4 − 2x4 + 7x4 = 8x4
d) 2a2bc3 − 5a2bc3 + 3a2bc3 − 2a2bc3 = −2a2bc3
Binomios:
a) (4x+5z)+(-2z+6x)=
4x +5z
6x -2z
-------------
R/ 10x+3z
b)(8x + 9y) - (3x - 2y) = 8x + 9y - 3x + 2y = R/ 5x + 11y
c) (5x + 8y) - (2x - 2y) = 5x + 8y - 2x + 2y = R/ 3x + 10y
d) (18x + 9y) + (15x - 4y) = 18x + 9y + 15x - 4y = R/ 33x + 5y
