Question

(1.) 9a³+5b²-10 ab - 6a³+b²-ab
(2.) 5m²+3mn+n - m²+6mn-7n² ​

Answer 1

Answer:

1) 9a³ + 5b² - 10ab - 6a³ + b ² - ab

9a³ - 6a³ + 5b² + b² - 10ab - ab

3a³ + 6b² - 11ab.

2) 5m² + 3mn + n - m² + 6mn - 7n²

5m² - m² + n + 3mn + 6mn - 7n²

4m² + n + 9mn - 7n²

This is the answer of the question...
