if q is the mean proportional between p and r prove that p²-q²+r²= q²[1/p²-1/q²+1/r²]

Question

if q is the mean proportional between p and r prove that p²-q²+r²= q²[1/p²-1/q²+1/r²]​

Eloise · Answer

Step-by-step explanation:   Answer. Since, q is the mean proportional of p and r. = p2 – pr + r2 = L.H.S. Hence proved.
