Question

(a²+b²) (a+b) (a-b) (a²-b²)
$(a {}^{2} + b { }^{2} )(a + b)(a - b)(a {}^{2} - b {}^{2} )$
​

Answer 1

Answer:

a^6-a^4 b² - a^4 b^2+b^6

Step-by-step explanation:

we have

(a+b) (a-b)= (a²-b²)

(a²+b²) (a+b) (a-b) (a²-b²)=(a²-b²)^2 (a²+b²)

= (a^4 +b^4 - 2 a^2 b^2 )(a²+b²)= a^6+a^4 b² + b^4 a^2 +b^6 - 2a^4 b^2 - 2a^2b^4

= a^6-a^4 b² - a^4 b^2+b^6
