Q. Fully simplify the expression below and write your answer as a single fraction.\newlinex+6x54x460x35x55x4450x3x2+12x+27 \frac{x+6}{x^{5}-4 x^{4}-60 x^{3}} \cdot \frac{5 x^{5}-5 x^{4}-450 x^{3}}{x^{2}+12 x+27} \newlineAnswer:
  1. Factor Denominator First Fraction: First, factor the polynomials in the numerator and the denominator where possible.\newlineStarting with the denominator of the first fraction: x54x460x3x^5 - 4x^4 - 60x^3.\newlineFactor out the common term x3x^3: x3(x24x60)x^3(x^2 - 4x - 60).\newlineNow factor the quadratic: x24x60=(x10)(x+6)x^2 - 4x - 60 = (x - 10)(x + 6).\newlineSo the denominator becomes: x3(x10)(x+6)x^3(x - 10)(x + 6).
  2. Factor Numerator Second Fraction: Next, factor the numerator of the second fraction: 5x55x4450x35x^5 - 5x^4 - 450x^3.\newlineFactor out the common term 5x35x^3: 5x3(x2x90)5x^3(x^2 - x - 90).\newlineNow factor the quadratic: x2x90=(x10)(x+9)x^2 - x - 90 = (x - 10)(x + 9).\newlineSo the numerator becomes: 5x3(x10)(x+9)5x^3(x - 10)(x + 9).
  3. Factor Denominator Second Fraction: Now, factor the denominator of the second fraction: x2+12x+27x^2 + 12x + 27.\newlineThis is a simple quadratic that factors to: (x+3)(x+9)(x + 3)(x + 9).
  4. Rewrite Expression with Factored Terms: We can now rewrite the entire expression with the factored terms:\newline(x+6)x3(x10)(x+6)5x3(x10)(x+9)(x+3)(x+9)\frac{(x+6)}{x^3(x - 10)(x + 6)} \cdot \frac{5x^3(x - 10)(x + 9)}{(x + 3)(x + 9)}
  5. Cancel Common Terms: Next, cancel out the common terms in the numerator and the denominator.\newlineThe x+6x + 6 terms cancel each other, as do the x10x - 10 terms and the x+9x + 9 terms.\newlineWe are left with:\newline5x3x3(x+3)\frac{5x^3}{x^3(x + 3)}
  6. Cancel Common x^33 Term: Now, cancel out the common x3x^3 term:\newline5x+3\frac{5}{x + 3}
  7. Final Simplified Answer: The expression is now fully simplified, and there are no more common terms to cancel.\newlineThe final answer is:\newline5x+3\frac{5}{x + 3}
