Step-by-step explanation:

(an+by) ²+ (by-an) ²

=2(an) ²+2(bn) ²

Answer 2

Answer:

so, (an+by) ²+ (bn-ay)² =( n²+ y²)(a²+b²)

Step-by-step explanation:

(an+by) ²+ (bn-ay)²

= a²n²+ b²y²+ 2abxn+b²n²+ a²y²-2abny

= a²(n²+ y²)+b²(n²+y²)

= (n²+ y²)(a²+b²)

so, (an+by)² + (bn-ay)² = (n²+ y²)(a²+b²)
