Identify GCF: Identify the greatest common factor (GCF) of the terms in the expression 6x3−x. The terms 6x3 and −x both have a common factor of x.
Factor out GCF: Factor out the GCF from the expression.6x3−x=x(6x2−1)
Check for further factorization: Check if the remaining expression inside the parentheses can be factored further.The expression 6x2−1 is a difference of squares since it can be written as (6x)2−12.
Factor difference of squares: Factor the difference of squares using the identity a2−b2=(a+b)(a−b). 6x2−1=(6x+1)(6x−1)
Write final factored form: Write the final factored form of the original expression by combining the GCF factored out in Step 2 with the factored form from Step 4.6x3−x=x(6x+1)(6x−1)
