Det of 2x2 matrix formula

WebA determinant is a property of a square matrix. The value of the determinant has many implications for the matrix. A determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's ... WebIn other words, to take the determinant of a 2×2 matrix, you follow these steps: Multiply the values along the top-left to bottom-right diagonal. Multiply the values along the bottom-left to top-right diagonal. Subtract the second product from the first. Simplify to get the value of the 2-by-2 determinant. "But wait!"
