# Factor Polynomial Calculator



A calculator to factor Polynomials is presented. You may also want to review factoring polynomials by common Factor , factoring polynomials by grouping and

## Factor Polynomials

Factroring a polynomial over the real is to write it as a product of linear, quadratic and may be other polynomials using real numbers only.
Example
The polynomial $P(x) = x^4+x^3+7x^2+9x-18$ may factored (written as a product) as $P(x) = \left(x-1\right)\left(x+2\right)\left(x^2+9\right)$

## Use of the Factoring of Polynomials Calculator

1 - Enter and edit function $P(x)$ and click "Enter Polynomial" then check what you have entered and edit if needed.
Note that the five operators used are: + (plus) , - (minus), / (division) , ^ (power) and * (multiplication). (example: P(x) = 2*x^2 + 3*x - 5).(more notes on editing functions are located below)
2 - Click "Factor Polynomial" to obain the factoring if possible.
3 - Note This calculator can factor over the rationals only.If a polynomial cannot be factored over the rational numbers, then the same polynomial (withour factoring) is output.

$P(x)$ =

Notes: In editing functions, use the following:
1 - The five operators used are: + (plus) , - (minus), ^ (power) and * (multiplication). (example: P(x) = -x^2 + 5x - 6 )
Here are some examples of functions that you may copy and paste to practice:
x^2 + 2x - 3       -x^2 + 5x - 6       -x^3+4x^2+5x       x^4 - 16       x^4+2x^3-7x^2-8x+12
x^3 + 1       x^4-2x^3-4x^2+2x+3       -2x^4+8x^3+14x^2-44x-48
