Evaluating the expression you entered
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:
x2(x2-3x-40)Attach our factored out piece from the beginning of our calculation for our final expression:
x2(x2 - 3x - 40)How does the Factoring and Root Finding Calculator work?

What 3 formulas are used for the Factoring and Root Finding Calculator?
a2 - b2 = (a + b)(a - b)
a3 + b3 = (a + b) (a2 - ab + b2)
a3 - b3 = (a - b) (a2 + ab + b2)
For more math formulas, check out our Formula Dossier
a3 + b3 = (a + b) (a2 - ab + b2)
a3 - b3 = (a - b) (a2 + ab + b2)
