Question

Simplify (x² + y²) (x² + y²) − (x² −y²)(x² − y²)​

Answer 1

Answer:

For my way the ans is zero

Explanation:

The 1 formula of indices a²+a²=a²-²=0

Therefore x²+y² + x² +y²- x²+y²+x²+y²

So the ans is 0. Th sings will be change .

Answer 2

Answer:

using the expnsions formula the answer is 4x²y².

(x² + y²) (x² + y²) − (x² −y²)(x² − y²)

the aboveequation can be written as:

(x² + y²)²-(x² −y²)² ...expand using formula.

((x² )² +(y² )²+2*x² *y² )-((x² )² +(y² )² -2*x² *y²)

(x⁴+y⁴+2x²y²)-(x⁴+y⁴-2x²y²)....openong the bracket.

x⁴+y⁴+2x²y²-x⁴-y⁴+2x²y².....

4x²y²....answer.

So, after factorisation the answer becomes 4x²y².
