Determine factoring technique: Determine the appropriate factoring technique for 1−x2.The expression is a difference of squares, which can be factored using the formula a2−b2=(a−b)(a+b).Here, 1=12 and x2=(x)2, so 1−x2 is in the form of a2−b2.
Apply difference of squares formula: Apply the difference of squares formula to factor the expression.Using the formula a2−b2=(a−b)(a+b), we can write 1−x2 as (1−x)(1+x).
Check for mathematical errors: Check for any mathematical errors in the factoring process.The factored form (1−x)(1+x) correctly represents the original expression 1−x2 when multiplied out.
