समीकरण \(\begin{vmatrix}a-x&c&b\\ c&b-x&a\\ b&a&c-x\end{vmatrix}\) = 0.

R1, के सापेक्ष विस्तार करने पर,

(-x) [(c – a) (a – c + x) – (b – c + x) (b – x – a)] = 0 la- * c b|

(-x) [(ac – c2 + cx – a2 + ac – ax) – (b2 – bx – ab – bc + cx + ac – xb – x2 – ax)]

(-x) [x2 – (a2 + b2– ab – bc – bc – ca)]= 0

यदि – x = 0, तो x = 0

अब यदि x2 – (a2 + b2 + c2+ c2– ab – ca) = 0
