If A and B are square matrices of the same order, then (A + B)(A − B – InterviewSolution

1.	If A and B are square matrices of the same order, then (A + B)(A − B) is equal to(a) A2 − B2(b) A2 − BA − AB − B2(c) A2 − B2 + BA − AB(d) A2 − BA + B2 + AB
Answer» If A and B are square matrices of the same order, then (A + B)(A − B) is equal to (a) A² − B² (b) A² − BA − AB − B² (c) A² − B² + BA − AB (d) A² − BA + B²+ AB
