Partial Fractions Decomposition Rules

The present online calculator uses the rules of partial fractions decomposition to write complex rational functions as a sum of simpler fraction.


Use of the Fractions Decomposition Calculator

1 - Enter and edit the expression to decompose and click "Enter Expression" then check what you have entered.
2 - The four operators used are: + (plus) , / divide , - (minus) , ^ (power) and * (multiplication). (example: (4x^2-x+8) / ((x-2)*(x^2+2x+3)) )
2 - Click "Decompose" to obain the expanded and simplified expression.
Note that the * is needed when multiplying expressions.


Expression:    






Notes: In editing functions, use the following:
Here are some examples of expressions that you may copy and paste to practice:
x/(x^2-4)             (2 x + 5)/(x^2-9)             (2 x + 5)/(x^2-x-2)           (-x + 7)/(x^2+x-2)             (x^2+6x - 3)/((x+3)*(x^2+2x+9))
(-8x^2 +23x - 5)/((x+7)*(2x^2+x+2))           (2x^3 + 10x^2 +11x)/(x^2+5x+6)             (x^4+3x^3+2x^2+7x+9)/(x^2+3x+2)
