Understand given expression: Understand the given expression.We have the expression (1−x1)/(1−x21). We need to simplify this expression by performing the operations in the numerator and the denominator.
Simplify numerator: Simplify the numerator.The numerator is 1−(1/x). To simplify this, we can find a common denominator, which is x.1−(1/x)=(x/x)−(1/x)=(x−1)/x
Simplify denominator: Simplify the denominator.The denominator is 1−(1/x2). To simplify this, we can find a common denominator, which is x2.1−(1/x2)=(x2/x2)−(1/x2)=(x2−1)/x2
Rewrite original expression: Rewrite the original expression with the simplified numerator and denominator.Now we have the expression with the simplified numerator and denominator:x(x−1) / x2(x2−1)
Divide fractions: Divide the fractions.To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.(xx−1)×(x2−1x2)
Simplify expression: Simplify the expression.We notice that x in the numerator of the first fraction and x2 in the numerator of the second fraction can be simplified.xx−1×x2−1x2=(x−1)×(xx)×(x2−1x)=(x−1)×(1)×(x2−1x)=(x−1)×(x2−1x)
Factor denominator: Factor the denominator.The denominator x2−1 is a difference of squares and can be factored as (x+1)(x−1).(x−1)∗((x+1)(x−1)x)
Cancel common terms: Cancel out the common terms.We have (x−1) in both the numerator and the denominator, so we can cancel them out.(x−1)×(x+1)(x−1)x = \frac{x}{x + 1}
