Simplifying the Expression: (x + 1)  (x  2)  (x + 3)
This expression involves multiple terms with parentheses, which we need to simplify to get a single expression.
Understanding the Process
 Distribute the Negative Signs: The minus signs before the second and third parentheses indicate we need to distribute them to the terms inside. This means multiplying each term inside the parentheses by 1.
 Combine Like Terms: After distributing the negative signs, we'll have terms with 'x' and constant terms. We can then combine these like terms.
StepbyStep Solution

Distribute the Negative Signs: (x + 1)  (x  2)  (x + 3) = x + 1  x + 2  x  3

Combine Like Terms: x + 1  x + 2  x  3 = (x  x  x) + (1 + 2  3)

Simplify: (x  x  x) + (1 + 2  3) = x
Final Answer
Therefore, the simplified form of the expression (x + 1)  (x  2)  (x + 3) is x.
