Question

if a/b=b/c=c/d then show that (b+c)²= (a+d)(c+d)​

Answer 1

Answer:

equate

a/b=b/c=c/d = k where k is just a constant

a = kb --- 1

b = kc ----2

c = kd -----3

solve the rhs part with this by equating the values of a,c and d with the help of equations 1,2 and 3 and then you will get the answer....
