hello,

Can someone please help me with this problem?

(I+2A)^-1 = [ -1 2 ]

[ 4 5 ]

not sure how to make a matrix...

it's suppose to be a 2 x 2 matrix with row 1 = -1, 2 and row 2 = 4, 5

Thanks!

What i'm stumped with is I, what do you have to do with it?

from the looks of it, since the matrix for the identity is row 1 = [1 0] row 2 = [0 1]

just subtract 1? when you move the I to the right side? - Oct 7th 2010, 10:38 PMtonio
