Question

(mn-kl+km)(kl-lm) find the product

Answer 1

Hi Friend ✋✋

( mn - kl + km ) × ( kl - lm )

by Distributive property,

= [( kl - lm ) × mn ] - [ ( kl - lm ) × kl ] + [ ( kl - lm ) × lm ]

= [ mnkl - m²nl ] - [ k²l² - kl²m ] + [ kl²m - l²m² ]

= mnkl - m²nl - k²l² +kl²m + kl²m - l²m²

= mnkl - m²nl - k²l² + 2kl²m - l²m²

hope it helps
