Multiple Choice

A quality control technician is auditing a technical specification that uses the algebraic model z2−4z−5z^2 - 4z - 5 for stress testing. To ensure the factored model (z+1)(z−5)(z + 1)(z - 5) provided in the documentation is correct, the technician performs a multiplication check. According to the trinomial factoring strategy, which expression represents the correct intermediate step in the expansion of (z+1)(z−5)(z + 1)(z - 5) before the middle terms are combined?
