To solve the expression \(4x^3 - 4x\), we can factor out the greatest common factor from the terms. The greatest common factor here is \(4x\). After factoring, we can simplify the expression.
Step 1: Factor the Expression
We start with the expression \(4x^3 - 4x\). To simplify it, we factor out the greatest common factor, which is \(4x\):
\[
4x^3 - 4x = 4x(x^2 - 1)
\]
Step 2: Further Factorization
The term \(x^2 - 1\) is a difference of squares, which can be factored further:
\[
x^2 - 1 = (x - 1)(x + 1)
\]
Thus, we can rewrite the expression as:
\[
4x(x^2 - 1) = 4x(x - 1)(x + 1)
\]
Final Answer
The fully factored form of the expression \(4x^3 - 4x\) is:
