Q. Express x−x2−2x−311+x−32 as a single fraction in its simplest form
Factor Denominator: Factor the denominator of the first fraction.The denominator x2−2x−3 can be factored into (x−3)(x+1) because (x−3)(x+1)=x2+x−3x−3=x2−2x−3.
Rewrite First Fraction: Rewrite the first fraction with the factored denominator.The first fraction becomes (x−11)/((x−3)(x+1)).
Combine Fractions: Combine the two fractions.Since the second fraction already has a denominator of (x−3), we can combine the two fractions by writing them over a common denominator, which is (x−3)(x+1).The combined fraction is (x−3)(x+1)x−11+2(x+1).
Distribute and Combine: Distribute and combine like terms in the numerator.Distribute the 2 in the second term of the numerator to get 2x+2.The numerator becomes (x−11+2x+2).Combine like terms to get (3x−9).
Write Simplified Fraction: Write the simplified fraction.The simplified fraction is (3x−9)/((x−3)(x+1)).
Check Numerator Factor: Check if the numerator can be factored further.The numerator 3x−9 can be factored as 3(x−3).
Cancel Common Factors: Cancel common factors.The factor (x−3) is common to both the numerator and the denominator, so we can cancel it out.The final simplified fraction is (x+1)3.
