Question

solve using identity (a2 + b2)(-a2 + b2)

Answer 1

(a² + b²) (-a² + b²)

Rearrange the terms:

= (b² + a²)(b² - a²)

Apply (b + a)(b - a) = b² - a²

= (b²)² - (a²)²

Evaluate the exponents:

= b⁴ - a⁴

Answer 2

Hey dear friend,

(b²+a²)(b²-a²)
by identity (b+a)(b-a)=b²-a²

So,
the answer is =>b⁴-a⁴

perfectly fine pure correct answer.
