Q. Perform the following operation and express in simplest form.\newlinex2+11x+24x29÷4x+32x3 \frac{x^{2}+11 x+24}{x^{2}-9} \div \frac{4 x+32}{x^{3}} \newlineAnswer:
  1. Identify and Rewrite Division: Identify the given expression and rewrite the division as multiplication by the reciprocal of the second fraction.\newlineThe expression is (x2+11x+24)/(x29)÷(4x+32)/(x3)(x^2 + 11x + 24)/(x^2 - 9) \div (4x + 32)/(x^3).\newlineRewrite as (x2+11x+24)/(x29)×(x3)/(4x+32)(x^2 + 11x + 24)/(x^2 - 9) \times (x^3)/(4x + 32).
  2. Factor Numerators and Denominators: Factor the numerator and denominator of the first fraction and the numerator of the second fraction.\newlineThe numerator x2+11x+24x^2 + 11x + 24 can be factored into (x+8)(x+3)(x + 8)(x + 3).\newlineThe denominator x29x^2 - 9 is a difference of squares and can be factored into (x+3)(x3)(x + 3)(x - 3).\newlineThe numerator 4x+324x + 32 of the second fraction can be factored out by 44 to get 4(x+8)4(x + 8).\newlineThe expression becomes (x+8)(x+3)(x+3)(x3)×x34(x+8)\frac{(x + 8)(x + 3)}{(x + 3)(x - 3)} \times \frac{x^3}{4(x + 8)}.
  3. Cancel Common Factors: Cancel out common factors from the numerator and denominator.\newlineThe (x+8)(x + 8) terms cancel out, and the (x+3)(x + 3) terms cancel out.\newlineThe expression simplifies to 1(x3)×x34\frac{1}{(x - 3)} \times \frac{x^3}{4}.
  4. Multiply Remaining Expressions: Multiply the remaining expressions.\newlineMultiplying 1(x3)\frac{1}{(x - 3)} by x34\frac{x^3}{4} gives x34(x3)\frac{x^3}{4(x - 3)}.
  5. Check for Further Simplification: Check for any further simplification. There are no common factors to cancel out, and the expression is already in its simplest form.
