Question

i) (a^2 + b^2) (- a^2+ b^2)​

Answer 1

Step-by-step explanation:

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

(a²+2ab+b²) (a²-2ab+b²)

Answer 2

Answer:

b^4 - a^4

Step-by-step explanation:

This question set to be on formula

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

Firstly we improve the question in form of formula

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

Here a=b^2 and b=a^2

So by the formula we get

b^4 - a^4 ans
