Step 1

1 of 9To find the determinant, we will multiply the scalars from the second row by the corresponding cofactors of the entries, and then we will sum them up.

Since we have $4\times 4$ matrix, the minors will be $3\times 3$ matrices. So to find the corresponding cofactors, we will expand by cofactors one more time.
