Q. Fully simplify the expression below and write your answer as a single fraction.\newlinex210x260x+80x210x+24x59x4+18x3 \frac{x-2}{10 x^{2}-60 x+80} \cdot \frac{x^{2}-10 x+24}{x^{5}-9 x^{4}+18 x^{3}} \newlineAnswer:
  1. Factor Quadratic Polynomials: First, factor the quadratic and cubic polynomials in the numerator and denominator where possible.
  2. Factor Cubic Polynomial: Factor the quadratic polynomial in the numerator: x210x+24x^2 - 10x + 24.\newlineThis factors into (x4)(x6)(x-4)(x-6) because 4-4 and 6-6 are the roots that satisfy the equation x210x+24=0x^2 - 10x + 24 = 0.
  3. Rewrite with Factored Forms: Factor the quadratic polynomial in the denominator: 10x260x+8010x^2 - 60x + 80.\newlineThis factors into 10(x26x+8)10(x^2 - 6x + 8), and further into 10(x4)(x2)10(x-4)(x-2) because 4-4 and 2-2 are the roots that satisfy the equation x26x+8=0x^2 - 6x + 8 = 0.
  4. Cancel Common Factors: Factor the cubic polynomial in the denominator: x59x4+18x3x^5 - 9x^4 + 18x^3.\newlineThis factors into x3(x29x+18)x^3(x^2 - 9x + 18), and further into x3(x3)(x6)x^3(x-3)(x-6) because 3-3 and 6-6 are the roots that satisfy the equation x29x+18=0x^2 - 9x + 18 = 0.
  5. Simplify Expression: Now, rewrite the original expression with the factored forms:\newline(x2)10(x4)(x2)(x4)(x6)x3(x3)(x6)\frac{(x-2)}{10(x-4)(x-2)} * \frac{(x-4)(x-6)}{x^3(x-3)(x-6)}.
  6. Simplify Expression: Now, rewrite the original expression with the factored forms:\newline(x2)10(x4)(x2)(x4)(x6)x3(x3)(x6)\frac{(x-2)}{10(x-4)(x-2)} * \frac{(x-4)(x-6)}{x^3(x-3)(x-6)}.Cancel out the common factors in the numerator and the denominator:\newlineThe (x2)(x-2) terms cancel, and the (x4)(x-4) and (x6)(x-6) terms cancel.
  7. Simplify Expression: Now, rewrite the original expression with the factored forms:\newline(x2)10(x4)(x2)(x4)(x6)x3(x3)(x6)\frac{(x-2)}{10(x-4)(x-2)} * \frac{(x-4)(x-6)}{x^3(x-3)(x-6)}.Cancel out the common factors in the numerator and the denominator:\newlineThe (x2)(x-2) terms cancel, and the (x4)(x-4) and (x6)(x-6) terms cancel.The simplified expression is now:\newline110x3(x3)\frac{1}{10x^3(x-3)}.
