0=-407x^2+220275x-19824750

解答

0 = - 407 x^{2} + 220275 x - 19824750

解答

x = \frac{- 22027 5 ^{2} - 32274693000 + 220275}{814}, x = \frac{22027 5 ^{2} - 32274693000 + 220275}{814}

+1

十进制

x = 114.02174 \dots, x = 427.19446 \dots

求解步骤

0 = - 407 x^{2} + 220275 x - 19824750

交换两边

- 407 x^{2} + 220275 x - 19824750 = 0

使用求根公式求解

x_{1, 2} = \frac{- 220275 \pm 22027 5 ^{2} - 4 ( - 407 ) ( - 19824750 )}{2 ( - 407 )}

22027 5^{2} - 4 (- 407) (- 19824750) = 22027 5^{2} - 32274693000

x_{1, 2} = \frac{- 220275 \pm 22027 5 ^{2} - 32274693000}{2 ( - 407 )}

将解分隔开

x_{1} = \frac{- 220275 + 22027 5 ^{2} - 32274693000}{2 ( - 407 )}, x_{2} = \frac{- 220275 - 22027 5 ^{2} - 32274693000}{2 ( - 407 )}

x = \frac{- 220275 + 22027 5 ^{2} - 32274693000}{2 ( - 407 )} : \frac{- 22027 5 ^{2} - 32274693000 + 220275}{814}

x = \frac{- 220275 - 22027 5 ^{2} - 32274693000}{2 ( - 407 )} : \frac{22027 5 ^{2} - 32274693000 + 220275}{814}

二次方程组的解是:

x = \frac{- 22027 5 ^{2} - 32274693000 + 220275}{814}, x = \frac{22027 5 ^{2} - 32274693000 + 220275}{814}

流行的例子

x^{2} = 5 (x - 1.2)

z^{2} + 2 + 1 = 0

2 t^{2} - 3 t - 3 = 0

(x + 2)^{2} = 4 x

solvefor x,ff=x^2

so l v e f or x, ff = x^{2}
