Full solution

Q. Express x11x22x3+2x3x-\frac{11}{x^2-2x-3} + \frac{2}{x-3} as a single fraction in its simplest form
  1. Factor Denominator: Factor the denominator of the first fraction.\newlineThe denominator x22x3x^2 - 2x - 3 can be factored into (x3)(x+1)(x - 3)(x + 1) because (x3)(x+1)=x2+x3x3=x22x3(x - 3)(x + 1) = x^2 + x - 3x - 3 = x^2 - 2x - 3.
  2. Rewrite First Fraction: Rewrite the first fraction with the factored denominator.\newlineThe first fraction becomes (x11)/((x3)(x+1))(x - 11)/((x - 3)(x + 1)).
  3. Combine Fractions: Combine the two fractions.\newlineSince the second fraction already has a denominator of (x3)(x - 3), we can combine the two fractions by writing them over a common denominator, which is (x3)(x+1)(x - 3)(x + 1).\newlineThe combined fraction is x11+2(x+1)(x3)(x+1)\frac{x - 11 + 2(x + 1)}{(x - 3)(x + 1)}.
  4. Distribute and Combine: Distribute and combine like terms in the numerator.\newlineDistribute the 22 in the second term of the numerator to get 2x+22x + 2.\newlineThe numerator becomes (x11+2x+2)(x - 11 + 2x + 2).\newlineCombine like terms to get (3x9)(3x - 9).
  5. Write Simplified Fraction: Write the simplified fraction.\newlineThe simplified fraction is (3x9)/((x3)(x+1))(3x - 9)/((x - 3)(x + 1)).
  6. Check Numerator Factor: Check if the numerator can be factored further.\newlineThe numerator 3x93x - 9 can be factored as 3(x3)3(x - 3).
  7. Cancel Common Factors: Cancel common factors.\newlineThe factor (x3)(x - 3) is common to both the numerator and the denominator, so we can cancel it out.\newlineThe final simplified fraction is 3(x+1)\frac{3}{(x + 1)}.
