If $Δ=-\begin{vmatrix}x^n&x^{n+2}&x^{2n}\\1&x^p&p\\x^{n+5}&x^{p+6}&x^{2n+5}\end{vmatrix}=0$, then p is equal to |
xn (n+ 1) either A or B both A and B |
both A and B |
Elements in C1 and C3 become proportional for p = xn and in R1 and R3 become proportional for p = n + 1. Hence (D) is the correct answer. |
