Factor x^4-3x^3-40x^2

<-- Enter Expression you want factored

Factor x4 - 3x3 - 40x2

Evaluating the expression you entered, we can factor out a variable portion of x2
Factor out x2 from 1x4
Our new x variable piece becomes: x(4 - 2) = x2
Our new term becomes x2

Factor out x2 from -3x3
Our new x variable piece becomes: x(3 - 2) = x1
Our new term becomes -3x

Factor out x2 from -40x2
Our new x variable piece becomes: x(2 - 2) = x0 = 1
Our new term becomes -40

Our factored expression is as follows:
x2(x2-3x-40)



Attach our factored out piece from the beginning of our calculation for our final expression:
x2(x2 - 3x - 40)
