Question

Factorize 27m3 -216n3​

Answer 1

Step-by-step explanation:

27m³ - 216 n³

(3m )³ - (6 n )³

apply (m³ - n³) formula = (m - n) ( m² + mn+ n²)

(3m - 6n) ( 3m ² + 3m x 6n + 6 n²)

(3m - 6n ) ( 9m² + 18mn + 36 n²)

or els u can take 3 common

then

3m³- 6 n³

3 ( m² - 2 n³)

3 ( m - 2n ) ( m²+ m x 2n + 2n²)

3 ( m- 2n ) ( m² + 2mn + 4 n²)
