Answer:
mnkl - m²nl - k²l² + 2kl²m - l²m²
Step-by-step explanation:
( 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
