6(s^20.167+s+1.333)=0

解答

6 (s^{2} 0.167 + s + 1.333) = 0

解答

s = \frac{- 6 + 3.944016}{2.004}, s = \frac{- 6 - 3.944016}{2.004}

+1

十进制

s = - 2.00301 \dots, s = - 3.98500 \dots

求解步骤

6 (s^{2} \cdot 0.167 + s + 1.333) = 0

展开

6 (s^{2} \cdot 0.167 + s + 1.333) : 1.002 s^{2} + 6 s + 7.998

1.002 s^{2} + 6 s + 7.998 = 0

使用求根公式求解

s_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1.002 \cdot 7.998}{2 \cdot 1.002}

6^{2} - 4 \cdot 1.002 \cdot 7.998 = 3.944016

s_{1, 2} = \frac{- 6 \pm 3.944016}{2 \cdot 1.002}

将解分隔开

s_{1} = \frac{- 6 + 3.944016}{2 \cdot 1.002}, s_{2} = \frac{- 6 - 3.944016}{2 \cdot 1.002}

s = \frac{- 6 + 3.944016}{2 \cdot 1.002} : \frac{- 6 + 3.944016}{2.004}

s = \frac{- 6 - 3.944016}{2 \cdot 1.002} : \frac{- 6 - 3.944016}{2.004}

二次方程组的解是:

s = \frac{- 6 + 3.944016}{2.004}, s = \frac{- 6 - 3.944016}{2.004}
