The characteristic equation of a (3 × 3) matrix P is defined as
a(λ) = |P - λ$$I$$| = λ3 + λ2 + 2λ + 1 = 0
If $$I$$ denotes identity matrix, then the inverse of matrix P will be
The characteristic equation of a (3 × 3) matrix P is defined as
a(λ) = |P - λ$$I$$| = λ3 + λ2 + 2λ + 1 = 0
If $$I$$ denotes identity matrix, then the inverse of matrix P will be Correct Answer - (P<sup>2</sup> + P+ 2$$I$$)
