簡約 ((x^2+1}{x^2})-4(\frac{x+1)/x)+6

解

簡約

(\frac{x ^{2} + 1}{x ^{2}}) - 4 (\frac{x + 1}{x}) + 6

\frac{x ^{2} + 1}{x ^{2}} - \frac{4 ( x + 1 )}{x} + 6

解答ステップ

(\frac{x ^{2} + 1}{x ^{2}}) - 4 (\frac{x + 1}{x}) + 6

規則を適用する:

(a) = a

(\frac{x ^{2} + 1}{x ^{2}}) = \frac{x ^{2} + 1}{x ^{2}}

= \frac{x ^{2} + 1}{x ^{2}} - 4 \cdot \frac{x + 1}{x} + 6

簡素化

4 \cdot \frac{x + 1}{x} : \frac{4 ( x + 1 )}{x}

= \frac{x ^{2} + 1}{x ^{2}} - \frac{4 ( x + 1 )}{x} + 6
