Question

Add:
(i) 5xy, - 2xy, - 11xy, 8xy
(ii) 3a - 2b + c, 5a + 8b - 7c
(iii) 3a²b, - 5a²b, 10a²b, - 7a²b
(iv) 4x² - 5xy + 3y², 8x² + 7xy - 6y², - 2x² - 9xy + 13y²
(v) a + b, 3a + 2b​

Answer 1

Answer:

1. 0

2. 8a-6b-6c

3. a^2b

4. 10x^2-7xy+10y^2

5. 4a+3b

Answer 2

Answer:

i) 5xy + ( - 2xy ) + ( - 11 xy) + 8xy

5xy - 2xy - 11 xy + 8xy

( 5 + 8 ) xy - ( 2 + 11 ) xy

13xy - 13xy = 0
