Answer 1

Explicación paso a paso:

a) 25x²-50x²+11x²+14x²

25x²-50x²+25x²

50x²-50x²

0

b) (3/5)a²b - (1/6)a²b + (1/3)a²b - a²b

(18/30)a²b - (5/30)a²b + (10/30)a²b - a²b

(23/30)a²b - (30/30)a²b

(-7/30)a²b

c) 7a - 9b + 6a - 4b + 6

13a - 13b + 6

a - b + 6/13

d) -a + b + 2b - 2c + 3a + 2c - 3b

2a + 3b - 3b

2a

e) (3/5)m²-2mn-(1/10)m²-(1/3)mn+2mn-2m²

(6/10)m²-(1/3)mn-(1/10)m²-2m²

(5/10)m²-2m² - (1/3)mn

(-15/10)m² - (1/3)mn

(-3/2)m² - (1/3)mn

f) x²+8xy-5y²+2x²+6y²-7xy -4 -2x²+2

x²+xy+y²-2
