Prove using properties : |43 3 6| |35 21 4|=0 |17 9 2| Share with your friends Share 1 Manbar Singh answered this Let ∆ = 4336352141792⇒∆=3431635741732Apply C1 = C1 - C2, we get∆=3421628741432⇒∆ = 21616474232⇒∆ = 21 × 0 as, C1 and C3 are identical, so ∆ = 0⇒∆ = 0 4 View Full Answer Devanshi Mittal answered this |43 3 6| |35 21 4| |17 9 2| Taking 3 common fron C2 =3 |43 1 6| |35 7 4| |17 3 2| C1= C1-C2 = 3 |42 1 6| |28 7 4| |14 3 2| Taking 7 common from C1 = 21 |6 1 6| |4 7 4| |2 3 2| Since 2 coloums are equal therefore Determinant=0 Hence proved 2
