To Find A 2×2 Determinant We Use A Simple Formula That Uses The Entries Of The 2×2 Matrix.
Determinant of a 2x2 matrix. So we wanna figure out the determinant of this matrix and we can denote it by the determinant of the 2x2 matrix five, three,negative one and four and the definition of determinant of the 2x2 matrix like this, as we can first take this diagonal, five times four so write it down, just going to be equal to 5 * 4 minus of. A 2×2 determinant is much easier to compute than the determinants of larger matrices, like 3×3 matrices.
Find The Determinant Of A Given 2X2 Matrix.
The problem says that the determinant results in 8, thus, we have to set the expression obtained equal to 8: Select any row or column find the cofactors of all the elements of the row or column that you have selected multiply the elements of the row or column by their corresponding cofactors add the products. In this case, a and d are diagonal elements.
