WebTo calculate the determinant of a 2×2 matrix. Step 1: Check if the given matrix is a square matrix that too a 2×2 matrix. Step 2: Identify all its rows and columns. Step 3: Put the values in the determinant formula, D 2×2 2 × 2 = ad - bc. The determinant formula for 2 by 2 matrix that is D 2×2 2 × 2 is given by ad - bc . Webd e t ( λ I − A c l) = d e t ( λ 2 I + ( λ + 1) k L e)) = 0. This is a determinant of a matrix of matrices, and they treat it like it is a 2x2 matrix determinant (and keep the det () operation after, which is even more confusing). If anybody could explain the mechanics behind this first part of the development I would be very grateful.
