Question

(a+b)×(a-b)³-(a-b)×(a+b)³

Answer 1

Answer:

(a+b) (a-b) (-4ab)

Step-by-step explanation:

take out (a+b) and (a-b) from the equation because they are common.

{ (a+b) × (a-b) } { (a-b)^2 - (a+b)^2 }

{a^2 -ab + ab -b^2} { (a-b+a+b) (a-b-a-b) }

(a^2-b^2) { (2a) (-2b) }

(a+b) (a-b) (-4ab)
