Question:medium

If A and B are 4x4 matrices such that $A^{2}+B=A^{2}B$ then which of the following is correct?

Show Hint

If a matrix $B$ can be expressed as a polynomial or rational function of matrix $M$, then $B$ and $M$ will always commute.

Updated On: Jul 4, 2026

$AB=I$
$A^{2}B=I$
$A^{2}B=BA^{2}$
$A^{2}=I$ or $B=I$

Show Solution
