Simplifying rational expressions requires factoring skills to find common factors in the numerator and denominator that can be canceled to reduce the expression. The document explains that factors common to both the top and bottom parts of a rational expression should be identified and canceled to simplify the expression, leaving a value of x that cannot be divided by the canceled factors.

2. Simplifying rational expressions
requires good factoring skills. The
twist now is that you are looking
for factors that are common to
both the numerator and the
denominator of the
rational expression.

3. what factors that are
common to the
numerator &
denominator?
3x

reduced,
state which values x
cannot hold

means to think clearly and
have sound judgment.
