Question

a2-b2+c2-d2-2(ac-bd)​

Answer 1

Answer:

Simplify: a2 - b2 + c2 - d2 - 2(ac - bd)

= a2 - b2 + c2 - d2 - 2ac - 2bd

= (a2 + c2 - 2ac) - (b2 + d2 - 2bd)

= (a - c)2 - (b - d)2

= (a - c + b - d) * (a - c - b +d) [From the property, a2 - b2 = (a + b)(a - b)]

= (a + b - c - d) * (a - b - c + d)

Answer 2
