Q. Simplify the following expression completely.\newlinex2+8x20x212x+20 \frac{x^{2}+8 x-20}{x^{2}-12 x+20} \newlineAnswer:
  1. Identify Factors: Identify the common factors in the numerator and the denominator. To do this, we need to factor both the numerator and the denominator.\newlineFactor the numerator: x2+8x20x^2 + 8x - 20.\newlineWe are looking for two numbers that multiply to 20-20 and add to 88. These numbers are 1010 and 2-2.\newlineSo, the factored form of the numerator is (x+10)(x2)(x + 10)(x - 2).
  2. Factor Numerator: Factor the denominator: x212x+20x^2 - 12x + 20. We are looking for two numbers that multiply to 2020 and add to 12-12. These numbers are 10-10 and 2-2. So, the factored form of the denominator is (x10)(x2)(x - 10)(x - 2).
  3. Factor Denominator: Now, we rewrite the expression with the factored numerator and denominator: (x+10)(x2)(x10)(x2)\frac{(x + 10)(x - 2)}{(x - 10)(x - 2)}.
  4. Rewrite Expression: Cancel out the common factors. We see that (x2)(x - 2) is a common factor in both the numerator and the denominator, so we can cancel it out: (x+10)(x10)\frac{(x + 10)}{(x - 10)}.
  5. Cancel Common Factors: The expression is now simplified to: \newline(x+10)/(x10)(x + 10) / (x - 10).\newlineThis is the simplest form of the expression, as there are no common factors left to cancel out.
