Question: Using the definition and properties listed in this section, show that for square matrices A and B of the same size, if AB = O

Using the definition and properties listed in this section, show that for square matrices A and B of the same size, if AB = O and if A exists, then B = O, where a matrix whose elements are all zeros. Given the matrix equation, AB = O, what should be the first step? O A. Left multiply both sides of the matrix equation by O O B. Left multiply both sides of the matrix equation by B - O C. Right multiply both sides of the matrix equation by O. O D. Right multiply both sides of the matrix equation by A O E. Right multiply both sides of the matrix equation by B - 1 OF. Left multiply both sides of the matrix equation by A" Perform the operation above AB = O Simplify the resulting equation Next
