M [-4 x]
Find the valueof x which would make M a non singular Matrix.
Can someone please explain to me how to do this? THanks
Definition: A non-singular matrix is a square matrix whose determinant is not zero.
Take the determinant of the 2x2 matrix given, which is ad - bc, set it to zero, then solve for x. You can conclude then if x is not the values you solved for, then the matrix will be non-singular.
