Q. −(a−1)(b−1)(c−1)Which of the following is equivalent to the given expression?Choose 1 answer:(A) (1−a)(b−1)(1−c)(B) (1−a)(1−b)(1−c)(C) (a−1)(1−b)(1−c)(D) (1−a)(1−b)(c−1)
Distribute Negative Sign: Distribute the negative sign across the expression.We need to distribute the negative sign to each term within the parentheses. This will change the sign of each term inside the parentheses.−(a−1)(b−1)(c−1)=(−1)⋅(a−1)(b−1)(c−1)Now, distribute the −1 to each term inside the first set of parentheses.(−1)⋅(a−1)=(1−a)
Apply Distribution: Apply the distributed negative sign to the other terms.Now, we apply the same logic to the other two sets of parentheses.(−1)⋅(b−1)=(1−b)(−1)⋅(c−1)=(1−c)
Combine Results: Combine the results from Step 1 and Step 2.Now we combine the results of distributing the negative sign to each term.(1−a)(1−b)(1−c)
Match with Options: Match the result with the given options.The expression we have obtained is 1−a)(1−b)(1−c)whichmatchesoption$B.
