So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. how to stop spending money on gamesWebIf A=⎣⎢⎢⎡12a212 2−2b ⎦⎥⎥⎤ is a matrix satisfying the equation AA T=9I, where I is 3× 3 identity matrix, then the ordered pair (a,b) is equal : A (2,−11) B (−2,1) C (2,1) D (−2,−1) … read my email inbox gmailWebif is a matrix satisfying the equation AAT=9I, where I is 3x3 identity matrix, then the ordered pair (a, b) is equal to : Option 1) Option 2) Option 3) Option 4) Browse by … read my email on aolWebThe concept of normal matrices can be extended to normal operators on infinite dimensional normed spaces and to normal elements in C*-algebras.
