Algebraic Fraction和Monomials
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 denomin
Monomials
An expression with only one term is called monomial.
Example:
3x,2x2,and 4xy are all monomials.
2x+1,x+y,3(x+1),and x+x2 are not monomials.
Remember:
There is no addition or subtraction in monomials.
Mono means one, as in monologue
ator to find the common factors.
