Question

Given `A = 2[(2, 1),(3, 0)],-3[(1, 1),(5, 2)] + [(-3, -1),(0,0)]` Find 2A - 3B + C

Solution

2A - 3B + C

= `2[(2, 1),(3, 0)] -3[(1,1),(5,2)] + [(-3,-1),(0,0)]`

`= [(4,2),(6, 0)] - [(3,3),(15, 6)] + [(-3,-1),(0 ,0)]`

`= [(4 - 3 - 3, 2-3-1),(6 - 15 + 0, 0 - 6 + 0)]`

`= [(-2 -2),(-9 -6)]`

  Is there an error in this question or solution?
