Question

(a²b-b²a)²
give accurate and correct answer​

Answer 1

Answer:

a⁴b² + b⁴a² - 2a³b³

Step-by-step explanation:

Formula / Identity : -

( x + y )² = x² + y² + 2xy

Here,

x = a²b

y = b²a

( a²b - b²a )²

= ( a²b )² + ( b²a )² - 2 ( a²b ) ( b²a )

= a⁴b² + b⁴a² - 2a³b³

Answer 2

Answer:

Given

(a2b-ab2)2

we use the identity,(a-b)=a2+b2-2ab

=(a2b)2 +(ab2)2-2(ab2) (a2b)

=a4b2+a2b4-2a3b3
