Question

Simplify :-- (a² - b² )²​

Answer 1

Answer:

(a²-b²)²

Step-by-step explanation:

Since, (a-b)² = a²-2ab+b²

= (a²)² - (2a²b²) + (b²)²

= a⁴- 2(ab)² + b⁴. ANS

Answer 2

Answer:

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

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

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

you can do this more

multiply this column to next column.otherwise there is no need.
