Hello...
Answer....

We have,

(3m-2n) (2m-3n)

= 3m ( 2m-3n) -2n (2m-3n)

= 3m × 2m - 3m × 3n - 2n × 2m + 2n × 3n

= 6m² - 9mn - 4mn + 6n²

= 6m² - 13mn + 6n²

When m = 1, n = -1, we get

(3m -2n ) (2m - 3n)

= 6m² - 13mn + 6n²

= 6 × (1)² - 13 × 1 × (-1) + 6 × (-1)² = 6 + 13 + 6 = 25


Hope it helped

<b>HERE IS THE ANSWER TO YOUR QUESTION!!

We have;

(3m-2n) (2m-3n)

=> 3m ( 2m-3n) -2n (2m-3n)

=> 3m × 2m - 3m × 3n - 2n × 2m + 2n × 3n

=> 6m² - 9mn - 4mn + 6n²

=> 6m² - 13mn + 6n²

When m = 1, n = -1, we get

(3m -2n ) (2m - 3n)

=> 6m² - 13mn + 6n²

= 6 × (1)² - 13× 1× (-1) +6 × (-1)² = 6 + 13 + 6 = 25
