1 ) 3a + b - 4b + 5a

= Solution,

= 3a + 5a +b - 4b

= 8a - 3b

2 ) x + 10x + 2y - 8

= Solution,

= x + 10x + 2y - 8

= 11x + 2y - 8

3 ) 10x² - 4 - 2x²+ x ²

= Solution,

= 10x² - 2x² + x ² - 4

= 9 x² - 4

4 ) 3b + a - b + 2a

= Solution,

= 3b - b + a + 2a

= 2b + 3a

5 ) 6y³ - y³- 2x² + x²

= Solution,

= 6y³ - y³ - 2x² + x²

= 5y³ - x²

6 ) -2y + 2 + 3y + 1

= Solution,

= - 2y + 3y +2 +1

= y + 3

7 ) 1 + 3x + 4x²- 5x + 8

= Solution,

= 1 + 8 + 3x - 5x + 4x²

= 9 - 2x + 4x²

8 ) 12 x + 3y + 6x + y

= Solution,

= 12x + 6x + 3y + y

= 18x + 4y

9 ) - 4a³ + 1 + a³ + 7a²

= Solution,

= -4a³ + a³ + 1 + 7a²

= 3a³ + 1 + 7a²

10 ) -2 + 35b - 8b - 2b

= Solution,

= -2 + 27b - 2b

= -2 + 25b

11) - 2b + 3ab + a + 9ab

= Solution,

=- 2b + 3ab + 9ab + a

= - 2b + 12ab + a

12 ) - x³ + 2x + 2x³ - x + x²

= Solution,

= - x³ + 2x³ + 2x - x + x²

= x³ + x + x²
