De:

1...

2x – 3y restar -x + 2y

2x - 3y - (-x + 2y)

2x - 3y + x - 2y

3x - 5y

2...

y^2 + 6y^3 - 8 restar 2y^4 – 3y^2 + 6y

y^2 + 6y^3 - 8 - (2y^4 - 3y^2 + 6y)

y^2 + 6y^3 - 8 - 2y^4 + 3y^2 - 6y

4y^2 + 6y^3 - 8 - 2y^4 - 6y

-2y^4 + 6y^3 + 4y^2 - 6y - 8

3...

5/9x^2 - 3/8y^2 restar 5/7xy + 1/10y^2 - 3/11

$\frac{5}{9}x^2 - \frac{3}{8}y^2 - (\frac{5}{7}xy +\frac{1}{10}y^2 - \frac{3}{11} )\\\\\frac{5}{9}x^2 - \frac{3}{8}y^2 - \frac{5}{7}xy -\frac{1}{10}y^2 + \frac{3}{11} \\\\\frac{5}{9}x^2 -\frac{19}{40}y^2 - \frac{5}{7}xy + \frac{3}{11}$

a - b + 2c de -a + 2b - 3c

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

-a + b - 2c - a + 2b - 3c

-2a + 3b - 5c

5...

m^2 + 7n - 8c + d de m^2 - 9n + 11c + 14

-(m^2 + 7n - 8c + d) + m^2 - 9n + 11c + 14

-m^2 - 7n + 8c - d + m^2 - 9n + 11c + 14

-16n + 19c - d + 14

19c - d - 16n + 14

6...

5/6a^3 - 7/8ab^2 + 6 de a^2b + 1/4ab^2 - 1/3

-(5/6a^3 - 7/8ab^2 + 6) + a^2b + 1/4ab^2 - 1/3

-5/6a^3 + 7/8ab^2 - 6 + a^2b + 1/4ab^2 - 1/3

-5/6a^3 + 9/8ab^2- 19/3 + a^2b

9/8ab^2 + a^2b - 5/6a^3 - 19/3
