The question is in the picture below. Could you please wire down the detailed calculation process? Thank you!

Suppose that M is a 3*3 real matrix with characteristic polynomial:+l de:(MM) 2x3 + 3x2 + 21+ 16. Where I i=sthe 3*3 identity matrix. Working over R, which one of the following expressions evaluates to the matrix (M I)'1?+' 6' a) b) %(M24M+ 61) 6' 1 2 ?(M +4M+61) 6' C) %(M24M+ 21) 6' d) %(M2+4_M+21)| e) %(M2+4M61)l
