Question

Question: ∆ = \(\left| \begin{matrix} 0 & p - q & a - b \\ p - p & 0 & x - y \\ b - a & y - x & 0 \end{matrix}...

∆ = ∣0p−qa−bp−p0x−yb−ay−x0∣\left| \begin{matrix} 0 & p - q & a - b \\ p - p & 0 & x - y \\ b - a & y - x & 0 \end{matrix} \right|is equal to

A

0

B

a + b

C

x + y

D

p + q

Answer

0

Explanation

Solution

It is a skew symmetric determinant of odd order and hence

∆ = 0.
