(7a + 5b)² + (5a + 7b)² = (7a)2 + (5b)2 + 2(35ab) + (5a)2 + (7b)2 + 2(35ab) = 49a2 + 25b2 + 70ab + 25a2 + 49b2 + 70ab = 49a2 + 25a2 + 25b2 + 49b2 + 70ab + 70 ab = 74a2 + 74b2 + 140ab

7a + 5b)² + (5a + 7b)² = (7a)2 + (5b)2 + 2(35ab) + (5a)2 + (7b)2 + 2(35ab) = 49a2 + 25b2 + 70ab + 25a2 + 49b2 + 70ab = 49a2 + 25a2 + 25b2 + 49b2 + 70ab + 70 ab = 74a2 + 74b2 + 140ab

(7a + 5b)² + (5a + 7b)²

= (7a)²+ (5b)² + 2(35ab) + (5a)² + (7b)² + 2(35ab)

= 49a² + 25b²+ 70ab + 25a² + 49b² + 70ab

= 49a² + 25a² + 25b² + 49b²+ 70ab + 70 ab

= 74a² + 74b² + 140ab
