" (ii) "(1,2)(3,-4),(5,-6),(19,8)

Show that the following four points in each jof the following are concyclic and find the equation of the circle on which they lie. (1,2),(3,-4),(5,-6),(19,8)

The inverse of [(1,2,4),(3,-19,7),(2,4,8)] is

Compute the following: {:[(-1,4,-6),(8,5,16),(2,8,5)]+[(12,7,6),(8,0,5),(3,2,4)]

Check , whether , (1)/(11)[{:(-1,8,alpha),(1,-19,14),(2,6,-5):}] is an inverse of A=[{:(1,2,5),(3,1,1),(4,2,1):}] , if so , that alpha =……

If alpha and beta are the roots of the equation, [1,5][(1,3),(-4,7)]^(2)[(7/19, -13/19),(4/19,1/19)]^(4) [(1,3),(-4,7)]^(2)[(x^2 - 5x + 5),(-3)] = [-4] , then the value of (2 - alpha)(2 - beta) is

Let A={1,2,3},\ B={5,6},\ C={4,7,8} . Then AuuBuuC={1,2,3,4,5,6,7,8}
