Which conditional and its converse are both true? . if x = 3, then x2 = 6.. if x = 2, then x2 = 4.. if x2 = 4, then x = 2.. if x = 1, then 2x = 2.. - i think its c but i dont know

To diagonalize an nxn matrix a means to find an invertible matrix p and a diagonal matrix d such that a pdp d p ap or [1 3 dh epap 3 let a=-3 -5 -3 3 3 1 step 1: find the eigenvalues of matrix a "2's" step 2: find the corresponding eigenvectors of a step 3: createp from eigenvectors in step 2 step 4 create d with matching eigenvalues.
