Explain why the formula is not valid for matrices. illustrate your argument with examples. (a + b)(a − b) = a2 − b2 the formula is not valid because in general, the distributive property is not valid for matrices. the formula is not valid because in general, b(−b) ≠ −b2 for matrices. the formula is not valid because in general, ab ≠ ba for matrices. the formula is not valid because in general, a(−b) ≠ −ab for matrices. select the pair of matrices, a and b, for which the formula is not valid.
