Q3/create a matrix A and 1- add fourth & fifth rows equal to [1 2 3] by using [1 2 31 A= 4 5 6 [7 8 9 9] OA([4,5],:)-[1 2 3;1 2 3] O a([4,5],:)= [1 2 3;1 2 3] O A((4,5),:) [1 2 3;1 2 3] O a(,[4,5])=[1 2 3;1 2 3]
Show that if A is square matrix that satisfies the equation 2 A² - A - I = O, then its inverse is A-¹ = 2 A-I. The equation 24² - A - I = O implies that ---Select--- ✓. It follows that ---Select--- ✓. Notice the last equation means that ---Select--- multiplied with A is the identity, which is what we wanted to prove.
