Question

(a²+b²) (a²+b²) - (a²-b²) (a²-b²) symplify step by step​

Answer 1

Answer:

a^4+2(a^2×b^2)+b^4

Step-by-step explanation:

(a^2+b^2)(a^2+b^2)-(a^2-b^2)(a^2-b^2)=a^2(a^2+b^2)+b^2(a^2+b^2)=a^4+a^2×b^2+b^2×a^2+b^4=a^4+2(a^2×b^2)+b^4

Answer 2

a^2(a^2+b^2)+b^2(a^2+b^2)-[

a^2(a^2-b^2)-b^2(a^2-b^2)]

a^4+a^2b^2+a^2b^2+b^4-

[a^4-a^2b^2+a^2b^2+b^4]

a^4+a^2b^2+a^2b^2+b^4-

a^4+a^2b^2+a^2b^2-b^4

4a^2b^2
