Answer 1

$\huge\boxed{Answer}$

a , b & c are in continuous proportion ,

& a/b = b/c

means , b² = ac -------(1)

Means , a , b & c are in Geometric progression.

Now ,

=> (a² + b²)(b² + c²)

=> (a² + ac) (ac + c²)

=> a(a + c) *c(a + c)

=> ac(a + c)²

From eq. (1)

=> b²(a + c)²

=> RHS

Hence Proof
