begin by grouping terms that have things in common



factor out the like terms by groups



factor out -1 from (1 - L)



now what?

k2and L2 shold read K and L squared but dont know how to write this on the computer

you could type k^2 and L^2 respectively

thanks for help

think its (K^2L-mn)(L-L)?

i suppose you meant (K^2L - mn)(L - 1)

that is the answer
