Question

if a, b, c are in continued proportion then prove that a/a+2b = a-2b /a-4c using k method​

Answer 1

Step-by-step explanation:

s per the question,

a, b, c are in continued proportion that means,

This implies that:

Given equation:

Consider LHS of this equation, we get

On multiplying numerator and denominator by (a - 2b), we get

Put

Which is equal to RHS

Therefore,

LHS = RHS

Hence, proved.
