Question: Find A 2X 2 Matrix Such That. Find a nonzero 2 x 2 matrix A such that AA has all zero entries . ?] A 2×2 determinant is much easier to compute than the determinants of larger matrices, like 3×3 matrices. To find a 2×2 determinant we use a simple formula that uses the entries of the 2×2 matrix. Diagonalize the matrix A by finding a nonsingular matrix S and a diagonal matrix D such that S^{-1}AS=D. If A = [(1,5),(7,12)] and B = [(9,1),(7,8)], find a matrix C such that 3A + 5B + 2C is a null matrix. Please explain your steps, thank you!

Q: Verify that (AB)T = BTAT. Want to see the step-by-step answer? (Linear Algebra) Let A be a 2 by 2 symmetric matrix. 2×2 determinants can be used to find the area of a parallelogram and to determine invertibility of a 2×2 matrix. Show transcribed image text. Nov 30, 2011 #2 What you speak of is called a nilpotent matrix. Therefore, our task is to find the unknown matrix X in such a way that, applied to the left-most matrix as a factor from the right, it would produce the zero 2x2-matrix. Assuming that X is a square matrix order 2, you must find a way such that elements will "cancel". = [0 0] 2) Provide an example of two 2×2 matrices A and B, neither of which is the zero matrix or the identity matrix, such that AB=BA.
