limit as x approaches 1 of (11x^2-99)/(x^2-20x+51)

解

x \to 1 lim (\frac{11 x ^{2} - 99}{x ^{2} - 20 x + 51})

解

- \frac{11}{4}

+1

十進法表記

- 2.75

解答ステップ

x \to 1 lim (\frac{11 x ^{2} - 99}{x ^{2} - 20 x + 51})

値を挿入する

x = 1

= \frac{11 \cdot 1 ^{2} - 99}{1 ^{2} - 20 \cdot 1 + 51}

簡素化

\frac{11 \cdot 1 ^{2} - 99}{1 ^{2} - 20 \cdot 1 + 51} : - \frac{11}{4}

= - \frac{11}{4}
