-2034x^2+170086x-6426=0

解答

- 2034 x^{2} + 170086 x - 6426 = 0

解答

x = \frac{- 17008 6 ^{2} - 52281936 + 170086}{4068}, x = \frac{17008 6 ^{2} - 52281936 + 170086}{4068}

+1

十进制

x = 0.03779 \dots, x = 83.58363 \dots

求解步骤

- 2034 x^{2} + 170086 x - 6426 = 0

使用求根公式求解

x_{1, 2} = \frac{- 170086 \pm 17008 6 ^{2} - 4 ( - 2034 ) ( - 6426 )}{2 ( - 2034 )}

17008 6^{2} - 4 (- 2034) (- 6426) = 17008 6^{2} - 52281936

x_{1, 2} = \frac{- 170086 \pm 17008 6 ^{2} - 52281936}{2 ( - 2034 )}

将解分隔开

x_{1} = \frac{- 170086 + 17008 6 ^{2} - 52281936}{2 ( - 2034 )}, x_{2} = \frac{- 170086 - 17008 6 ^{2} - 52281936}{2 ( - 2034 )}

x = \frac{- 170086 + 17008 6 ^{2} - 52281936}{2 ( - 2034 )} : \frac{- 17008 6 ^{2} - 52281936 + 170086}{4068}

x = \frac{- 170086 - 17008 6 ^{2} - 52281936}{2 ( - 2034 )} : \frac{17008 6 ^{2} - 52281936 + 170086}{4068}

二次方程组的解是:

x = \frac{- 17008 6 ^{2} - 52281936 + 170086}{4068}, x = \frac{17008 6 ^{2} - 52281936 + 170086}{4068}
