Factor the rational expression below:
We do this by factoring numerator and denominator separately first
Factor 8x
3 + 22x
2 - 6x
Evaluating the expression you entered
Factor out a term of
2xFactor out
2x from 8x
3Our new constant becomes 8 ÷ 2 = 4
Our new x variable piece becomes
x
(3 - 1) = x
2Our new term becomes 4x
2Factor out
2x from 22x
2Our new constant becomes 22 ÷ 2 = 11
Our new x variable piece becomes
x
(2 - 1) = x
1Our new term becomes 11x
Factor out
2x from -6x
Our new constant becomes -6 ÷ 2 = -3
Our new x variable piece becomes
x
(1 - 1) = x
0 = 1
Our new term becomes -3
Our factored expression is:
2x(4x
2 + 11x-3)
Attach our factored out piece from the beginning of our calculation for our final expression:
2x(4x2 + 11x - 3)
Factor 4x - 1
Our factored out term becomes:
Our factored rational expression is as follows:
2x(4x2 + 11x - 3) | |
(4x - 1) |
(4x - 1)

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)
