જો $3$ ભિન્ન વાસ્તવિક સંખ્યાઓ $a$,$b$,$c$ માટે $a^2(a + p) = b^2 (b + p) = c^2 (c + p)$ જ્યાં $p \in R$, થાય તો $bc + ca + ab$ ની કિમત મેળવો 

A

$-p$

B

$p$

C

$0$

D

$\frac{{{p^2}}}{2}$

Solution

If each value is $k$, then $a$,$b$,$c$ are roots of equation $x^3 + px^2 – k = 0$ $bc + ca + ab = 0$.
