Given F(x) = calculate the matrix JF 3 [2x1³ x2 x3³×4² [3x1 x2x3* x4 -3 25

Can you explain whether a 2×2 matrix with an entire row of zeros can have an inverse?

For matrices X=[xyzw] and 0=[0000], find the matrix 0X.

Can a matrix with zeros on the diagonal have an inverse? If so, find an example. If not, prove why not. For simplicity, assume a 22 matrix.
