A square matrix that is not invertible is called singular or … SpletA matrix is invertible if and only if its determinant is non-zero. So we first calculate the determinant of the matrix A. By the first column cofactor expansion, we have det (A) = 2 7 + x − 3 4 x = 2((7 + x)x − ( − 3)4) = 2(x2 + 7x + 12) = 2(x + 3)(x + 4). Thus the determinant of A is zero if and only if x = − 3 or x = − 4. mod real pool 3d pc
