Question

Factorising (ax + by)² + (ay − bx) ² + c ²(x ² + y ²)

Answer 1

Step-by-step explanation:

I think this is the answer

Answer 2

Answer:

(ax+by)²+(ay-bx)²+c²(x²+y²)

(ax)²+2axby+(by)²+(ay)²-2aybx+(bx)²+c²x²+c²y²

a²x²+b²y²+a²y²+b²x²+c²x²+c²y²

a²x²+c²x²+b²x²+b²y²+a²y²+c²y²

x²(a²+c²+b²)+y²(b²+a²+c²)

x²(a²+b²+c²)+y²(a²+b²+c²)

(x²+y²)(a²+b²+c²)
