Answer 1

Answer:

${a}^{2} - {b}^{2}$

Step-by-step explanation:

Reason:

The above question is a identity that is very important in terms of 'Algebra'

The identity goes like this:

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

Answer 2

Answer:

Step-by-step explanation:

using identity [a+b][a-b] = a^2-b^2

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

= a^4 - 4b^4
