-0.13633(x)^2-3.00066(x)+73.59566=24.91

解答

- 0.13633 (x)^{2} - 3.00066 (x) + 73.59566 = 24.91

解答

x = - \frac{3.00066 + 35.55322 \dots}{0.27266}, x = \frac{35.55322 \dots - 3.00066}{0.27266}

+1

十进制

x = - 32.87358 \dots, x = 10.86331 \dots

求解步骤

- 0.13633 x^{2} - 3.00066 (x) + 73.59566 = 24.91

整理后得

- 0.13633 x^{2} - 3.00066 x + 73.59566 = 24.91

将

24.91

para o lado esquerdo

- 0.13633 x^{2} - 3.00066 x + 48.68566 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 3.00066 ) \pm ( - 3.00066 ) ^{2} - 4 ( - 0.13633 ) \cdot 48.68566}{2 ( - 0.13633 )}

(- 3.00066)^{2} - 4 (- 0.13633) \cdot 48.68566 = 35.55322 \dots

x_{1, 2} = \frac{- ( - 3.00066 ) \pm 35.55322 \dots}{2 ( - 0.13633 )}

将解分隔开

x_{1} = \frac{- ( - 3.00066 ) + 35.55322 \dots}{2 ( - 0.13633 )}, x_{2} = \frac{- ( - 3.00066 ) - 35.55322 \dots}{2 ( - 0.13633 )}

x = \frac{- ( - 3.00066 ) + 35.55322 \dots}{2 ( - 0.13633 )} : - \frac{3.00066 + 35.55322 \dots}{0.27266}

x = \frac{- ( - 3.00066 ) - 35.55322 \dots}{2 ( - 0.13633 )} : \frac{35.55322 \dots - 3.00066}{0.27266}

二次方程组的解是:

x = - \frac{3.00066 + 35.55322 \dots}{0.27266}, x = \frac{35.55322 \dots - 3.00066}{0.27266}
