Q. Fully simplify the expression below and write your answer as a single fraction.\newlinex+6x2+9x+18x3x212xx311x2+28x \frac{x+6}{x^{2}+9 x+18} \cdot \frac{x^{3}-x^{2}-12 x}{x^{3}-11 x^{2}+28 x} \newlineAnswer:
  1. Factor Polynomials: First, factor the polynomials in the numerators and denominators where possible.\newlineThe denominator x2+9x+18x^2 + 9x + 18 can be factored into (x+3)(x+6)(x + 3)(x + 6).\newlineThe numerator x3x212xx^3 - x^2 - 12x can be factored by taking out a common factor of xx, resulting in x(x2x12)x(x^2 - x - 12). Further factoring the quadratic gives x(x4)(x+3)x(x - 4)(x + 3).\newlineThe denominator x311x2+28xx^3 - 11x^2 + 28x can be factored by taking out a common factor of xx, resulting in x(x211x+28)x(x^2 - 11x + 28). Further factoring the quadratic gives x(x4)(x7)x(x - 4)(x - 7).
  2. Rewrite with Factored Forms: Now, we rewrite the original expression with the factored forms: (x+6(x+3)(x+6))×(x(x4)(x+3)x(x4)(x7))\left(\frac{x + 6}{(x + 3)(x + 6)}\right) \times \left(\frac{x(x - 4)(x + 3)}{x(x - 4)(x - 7)}\right).
  3. Cancel Common Factors: Next, we cancel out the common factors in the numerator and the denominator. The (x+6)(x + 6) terms cancel each other out, as do the (x+3)(x + 3) terms and the xx terms. The (x4)(x - 4) terms also cancel each other out. This leaves us with 1(x7)\frac{1}{(x - 7)}.
  4. Final Simplification: The expression is now fully simplified, and no further simplification is possible. The final answer is 1(x7)\frac{1}{(x - 7)}.
