Question & Answer
Equivalent expression for −(a − 1)(b − 1)(c − 1)
1 Answer
Verified archiveThe given expression is −(a − 1)(b − 1)(c − 1). To find its equivalent expression, we’ll first simplify it.
1. Factor out the negative sign:
[
-(a – 1)(b – 1)(c – 1) = -(1 – a)(1 – b)(1 – c)
]
This occurs because ( -(x – y) = (y – x) ).
From the simplified form (-(1 – a)(1 – b)(1 – c)), we can see that it is equivalent to option b, where you have ( (1 – a)(1 – b)(1 – c) ).
Thus, the answer is b. (1 – a)(1 – b)(1 – c).
