新版GRE数学复习重要考点：Algebraic Fraction

An algebraic fraction is division of one polynomial by another. An algebraic fraction can be simplified by canceling the common factors between the numerator and denominator.

Example:

(x²-a²)/(x-a)=(x+a)*(x-a)/(x-a)=(x+a).

(x²-3x+2)/(x-1)=(x-2)(x-1)/(x-1)=(x-2).

Factor out both the numerator and denominator to find the common factors.
