Question

Find the product of (2m-l)(2l-m)
And find the product of (k+3m)(3m-k)

Answer 1

Answer:

(2m-l)(2l-m)

=> 2m(2l-m) -l(2l-m)

=> 4ml - 2m^2 - 2l^2 + ml

=> 5ml - 2m^2 - 2l^2

(k+3m)(3m-k)

=> k(3m-k) +3m(3m-k)

=> 3km -k^2+ 9m^2 -3km

=> 9m^2-k^2

Answer 2

Answer:

2m(2l-m) -l(2l-m)

4lm-lm-2msq-2lsq+ml

4lm-lm-3m sq-2lsq

3lm-2msq-2lsq
