12\frac{1}{2}

Step-by-step solution

4 steps
  1. Divide every term in the numerator and the denominator by the highest power of KK, which is K2K^2.

    lim⁡K→∞K2−2K+32K2+5K−3=lim⁡K→∞K2K2−2KK2+3K22K2K2+5KK2−3K2\lim_{K \to \infty} \frac{K^2 - 2K + 3}{2K^2 + 5K - 3} = \lim_{K \to \infty} \frac{\frac{K^2}{K^2} - \frac{2K}{K^2} + \frac{3}{K^2}}{\frac{2K^2}{K^2} + \frac{5K}{K^2} - \frac{3}{K^2}}
  2. Simplify the terms.

    lim⁡K→∞1−2K+3K22+5K−3K2\lim_{K \to \infty} \frac{1 - \frac{2}{K} + \frac{3}{K^2}}{2 + \frac{5}{K} - \frac{3}{K^2}}
  3. Apply the limit.

    As K→∞K \to \infty, terms of the form cKn\frac{c}{K^n} (where n>0n > 0) approach 0.

    1−0+02+0−0\frac{1 - 0 + 0}{2 + 0 - 0}
  4. Calculate the final value.

    12\frac{1}{2}
