Q. Fully simplify the expression below and write your answer as a single fraction.\newline4x528x432x32x510x412x3x6x213x+40 \frac{4 x^{5}-28 x^{4}-32 x^{3}}{2 x^{5}-10 x^{4}-12 x^{3}} \cdot \frac{x-6}{x^{2}-13 x+40} \newlineAnswer:
  1. Factor Common Terms: First, factor out the common terms in the numerator and the denominator of the first fraction. The numerator can be factored by taking out 4x34x^3, and the denominator can be factored by taking out 2x32x^3.
  2. Factor Quadratic Expressions: After factoring, the expression becomes: \newline(4x3(x27x8))/(2x3(x25x6))(4x^3(x^2 - 7x - 8))/(2x^3(x^2 - 5x - 6))\newlineNow, factor the quadratic expressions in the parentheses.
  3. Cancel Common Terms: The quadratic x27x8x^2 - 7x - 8 can be factored into (x8)(x+1)(x - 8)(x + 1). The quadratic x25x6x^2 - 5x - 6 can be factored into (x6)(x+1)(x - 6)(x + 1).
  4. Simplify Second Fraction: Now, the expression looks like this:\newline(4x3(x8)(x+1))/(2x3(x6)(x+1))(4x^3(x - 8)(x + 1))/(2x^3(x - 6)(x + 1))\newlineNotice that (x+1)(x + 1) and x3x^3 can be canceled out from the numerator and the denominator.
  5. Multiply Fractions: After canceling, the expression simplifies to: \newline(4(x8))/(2(x6))(4(x - 8))/(2(x - 6))\newlineNow, let's simplify the second fraction (x6)/(x213x+40)(x - 6)/(x^2 - 13x + 40).
  6. Cancel Terms: The quadratic x213x+40x^2 - 13x + 40 can be factored into (x5)(x8)(x - 5)(x - 8). So, the second fraction becomes (x6)/((x5)(x8))(x - 6)/((x - 5)(x - 8)).
  7. Simplify Constant Terms: Now, multiply the simplified first fraction by the second fraction: \newline(4(x8)2(x6))×x6(x5)(x8)(\frac{4(x - 8)}{2(x - 6)}) \times \frac{x - 6}{(x - 5)(x - 8)}\newlineNotice that (x8)(x - 8) can be canceled out from the numerator of the first fraction and the denominator of the second fraction.
  8. Final Simplified Expression: After canceling, the expression simplifies to:\newline(42(x6))×(x6)(x5)(\frac{4}{2(x - 6)}) \times \frac{(x - 6)}{(x - 5)}\newlineNow, (x6)(x - 6) can be canceled out from the numerator of the second fraction and the denominator of the first fraction.
  9. Final Simplified Expression: After canceling, the expression simplifies to:\newline(4)/(2(x6))×(x6)/(x5)(4)/(2(x - 6)) \times (x - 6)/(x - 5)\newlineNow, (x6)(x - 6) can be canceled out from the numerator of the second fraction and the denominator of the first fraction.After canceling, the expression simplifies to:\newline(4)/(2)×(1)/(x5)(4)/(2) \times (1)/(x - 5)\newlineSimplify the constant terms by dividing 44 by 22, which equals 22.
  10. Final Simplified Expression: After canceling, the expression simplifies to:\newline(4)/(2(x6))(x6)/(x5)(4)/(2(x - 6)) \cdot (x - 6)/(x - 5)\newlineNow, (x6)(x - 6) can be canceled out from the numerator of the second fraction and the denominator of the first fraction.After canceling, the expression simplifies to:\newline(4)/(2)(1)/(x5)(4)/(2) \cdot (1)/(x - 5)\newlineSimplify the constant terms by dividing 44 by 22, which equals 22.The final simplified expression is:\newline2/(x5)2/(x - 5)\newlineThis is the fully simplified form of the original expression written as a single fraction.
