Reduce los siguientes polinomios: a) 2a -7b +2b +5a= b) y +4m -3y +2m +2y = c) -8c +2c +6p +3c –p = d) 4x – 2x² + 6x² + x = e) 5y +3x -6x + y +2x =

a) 2a -7b +2b +5a=

2a - 7b + 2b + 5a
= (2 + 5)a - 7b
= 7a - 7b

b) y +4m -3y +2m +2y =

y + 4m - 3y + 2m + 2y
= (1 + 2 - 3)y + (4 + 2)m
= -2y + 6m

c) -8c +2c +6p +3c –p =

-8c + 2c + 6p + 3c –p
= (-8 + 2 + 3)c + (6 – 1)p
= -3c + 5p

d) 4x – 2x² + 6x² + x =

4x – 2x² + 6x² + x
= (4 + 6 - 1)x² + x
= 9x² + x

e) 5y +3x -6x + y +2x =

5y +3x -6x + y +2x = (5 + 1)y + (3 - 6 + 2)x
= 6y - x
