(3)Tap U.

•This factorizes the selected expression.

•Though the above two procedures are quite different, they both produce the same result.

[Interactive] menu operations come in handy in the following cases.

•When you want to use a command on an expression you are calculating

•When you want to use a command that requires multiple arguments

When you use the [Interactive] menu to access a command that requires multiple arguments or if you access a command without first highlighting an expression, the dialog box that appears shows the number of arguments, the contents of each argument, and the input sequence. This lets you perform your input without worrying about command syntax.

The following procedure shows an example of using the [Interactive] menu when three arguments need to be specified.

Example: To obtain the definite integral of x2 + 2x, 1 O x O 2
