Find the product: (2m – l)(2l – m)

1.	Find the product: (2m – l)(2l – m)
Answer» (2m – l) (2l – m) = 2m(2l – m) – l(2l – m) = 2m × 2l – 2m × m – l × 2l + l × m = 4lm – 2m² – 2l² + lm = 5lm – 2m² – 2l²

Answer»

(2m – l) (2l – m)

= 2m(2l – m) – l(2l – m)

= 2m × 2l – 2m × m – l × 2l + l × m

= 4lm – 2m² – 2l² + lm

= 5lm – 2m² – 2l²
