Best ResponseYou've already chosen the best response.1okay so to find the determinant of a 2 x 2 matrix, you do... dw:1443686132265:dw (1)  (2) where (1) is the product of 5 and 2 and (2) is the product of 1 and 4

Best ResponseYou've already chosen the best response.1Not quite, so (1) = product of 5 and 2, so (1) = 5 x 2 = ? (2) = product of 1 and 4, so (2) = 1 x 4 = ? and determinant = (1)  (2) so determinant = (5 x 2)  (1 x 4) = ?? so now try again
