MATRIX HELP - Find the Determinant
by: Staff

The question:

Given the matrix

−1 3 0
3 0 4
3 4 −2

find its determinant.
The determinant is:


The answer:

Matrix A

a b c
d e f
g h i

The determinant of matrix A

Det(A) = a (e i - h f) - d (b i - h c) + g (b f - e c)

Matrix A

−1 3 0
3 0 4
3 4 −2

Det(A) = (-1) * [0*(-2) - 4*4] - 3 * [3*(-2) - 4*0] + 3 * [3*4 - 0*0]

Det(A) = 70

The final answer to your question is: Det(A) = 70
