If A is a square matrix such that A^2=2I,then A^-1=?

Afina-wow [57]

$A^2=2I$

Recall that $I=AA^{-1}=A^{-1}A$ , so

$A^2=2(A^{-1}A)$

Multiply on the right by $A^{-1}$ and regroup terms:

$A^2A^{-1}=2(A^{-1}A)A^{-1}$

$A(AA^{-1})=2A^{-1}(AA^{-1})$

$A=2A^{-1}$

and finally solve for $A^{-1}$ :

$\boxed{A^{-1}=\dfrac12A}$
