Q. Simplify the following expression completely.\newlinex213x+30x212x+27 \frac{x^{2}-13 x+30}{x^{2}-12 x+27} \newlineAnswer:
  1. Factor Numerator and Denominator: Factor the numerator and the denominator.\newlineThe numerator x213x+30x^2 - 13x + 30 can be factored into (x10)(x3)(x - 10)(x - 3) because 1010 and 33 are the numbers that multiply to 3030 and add up to 13-13.\newlineThe denominator x212x+27x^2 - 12x + 27 can be factored into (x9)(x3)(x - 9)(x - 3) because 99 and 33 are the numbers that multiply to (x10)(x3)(x - 10)(x - 3)00 and add up to (x10)(x3)(x - 10)(x - 3)11.
  2. Rewrite with Factored Forms: Rewrite the expression with the factored forms.\newlineThe expression becomes (x10)(x3)(x9)(x3)\frac{(x - 10)(x - 3)}{(x - 9)(x - 3)}.
  3. Cancel Common Factors: Cancel out the common factors.\newlineThe (x3)(x - 3) term is present in both the numerator and the denominator, so they cancel each other out.\newlineThe expression simplifies to x10x9\frac{x - 10}{x - 9}.
  4. Check for Further Simplifications: Check for any further simplifications. There are no further simplifications possible, and there are no common factors left. The expression is now in its simplest form.
