Answer 2

Given:

(3m² + 6m - 2n) × (5n - 3m)

To find:

Solve by column method (3m² + 6m - 2n) × (5n - 3m)

Solution:

By column method multiply 3m² + 6m - 2n and 5n - 3m

 3m² + 6m - 2n

×            5n - 3m  

-9m³ - 18m² + 6mn

+                    30mn - 10n² + 15m²n

-9m³ - 18m² + 36mn - 10n² + 15m²n

Therefore, answer is -9m³ - 18m² + 36mn - 10n² + 15m²n
