簡約 5/(x^2)-x-12+3/(x^2)-16

解

簡約

\frac{5}{x ^{2}} - x - 12 + \frac{3}{x ^{2}} - 16

- x + \frac{8}{x ^{2}} - 28

解答ステップ

\frac{5}{x ^{2}} - x - 12 + \frac{3}{x ^{2}} - 16

簡素化

\frac{5}{x ^{2}} - x - 12 + \frac{3}{x ^{2}} - 16 : - x + \frac{5}{x ^{2}} + \frac{3}{x ^{2}} - 28

= - x + \frac{5}{x ^{2}} + \frac{3}{x ^{2}} - 28

簡素化

\frac{5}{x ^{2}} + \frac{3}{x ^{2}} : \frac{8}{x ^{2}}

= - x + \frac{8}{x ^{2}} - 28
