(-3,5),(3,1),(0,3),(-1,-4)

Name the quadrilateral formed, if any, by the following points, and give reasons for your answers: A(-1, -2), B(1, 0), C(-1, 2), D(-3, 0) (ii) A(-3, 5), B(3, 1), C(0, 3), D(-1, -4) (iii) A(4, 5), B(7, 6), C(4, 3), D(1, 2)

If A={:[(2,-3,-5),(-1,4,5),(1,-3,-4)]:} and B={:[(-1,3,5),(1,-3,-5),(-1,3,5)]:} show that AB = BA = 0, where 0 is the zero matrix of order 3xx3 .

If A=[(-1,1,-1),(3,-3,3),(5,-5,5)] and B=[(0,54,3),(1,-3,-3),(-1,4,4)] , find A^2B^2 .

IF A=[{:(1,5,3),(2,4,0),(3,-1,-5):}],B=[{:(2,-1,0),(0,-2,5),(1,2,0):}] then find 3A-4B'.

If A = [(1,5,3),(2,4,0),(3,-1,-5)], B = [(2,-1,0),(0,-2,5),(1,2,0)] then find 3A - 4B .

If A=[(1,-2,3),(-4,2,5)],B=[(1,3),(-1,0),(2,4)] then 2A+3B'=

[(1,3,-2),(-3,0,-5),(2,5,0)] =A [(1,0,0),(0,1,0),(0,0,1)] then, C_(2) rarr C_(2)-3C_(1) and C_(3) rarr C_(3) +2C_(1) gives... [(1,0,0),(3,-9,11),(-2,1,4)] =A [(-1,3,2),(0,-1,0),(0,0,-1)] [(1,0,0),(-3,-1,-4),(2,-9,11)] =A [(1,-3,2),(0,1,0),(0,0,1)] [(1,0,0),(-3,1,4),(-2,9,-11)] =A [(-1,3,2),(0,-1,0),(0,0,-1)] [(1,0,0),(-3,9,-11),(2,-1,4)] =A [(1,-3,2),(0,1,0),(0,0,1)]

If A={:[(2,-3),(0,1),(-1,4)],B={:[(-1,5),(2,-3),(0,1)],C={:[(4,-2),(0,-1),(3,5)], Find the matrices A + 4B - 3C

Let A=[(-1 ,1,-1),(3,-3 ,3),( 5, 5, 5)] and B=[(0 ,4 ,3 ),(1,-3,-3),(-1 ,4 ,4)] , compute A^2-B^2 .
