How to Find the Determinant of a 3X3 Matrix: 12 Steps

WebLet's start with a 3x3 determinant. a₁ a₂ a₃ b₁ b₂ b₃ c₁ c₂ c₃ If we multiply it out, we get: a₁b₂c₃ - a₁b₃c₂ + a₂b₃c₁ - a₂b₁c₃ + a₃b₁c₂ - a₃b₂c₁ Notice how each term has an a, b, and c in it and also has a 1, 2, and 3 in it. This is why it works to use any row or column. Whichever row or column you use is the one you're factoring out.
