565.26x^{(2)}-11195x+26725=1616748

解答

565.26 x^{(2)} - 11195 x + 26725 = 1616748

解答

x = \frac{1119500 + 111950 0 ^{2} + 3.59511 E 13}{113052}, x = \frac{1119500 - 111950 0 ^{2} + 3.59511 E 13}{113052}

+1

十进制

x = 63.85588 \dots, x = - 44.05084 \dots

求解步骤

565.26 x^{(2)} - 11195 x + 26725 = 1616748

在两边乘以

100

56526 x^{2} - 1119500 x + 2672500 = 161674800

将

161674800

para o lado esquerdo

56526 x^{2} - 1119500 x - 159002300 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 1119500 ) \pm ( - 1119500 ) ^{2} - 4 \cdot 56526 ( - 159002300 )}{2 \cdot 56526}

(- 1119500)^{2} - 4 \cdot 56526 (- 159002300) = 111950 0^{2} + 3.59511 E 13

x_{1, 2} = \frac{- ( - 1119500 ) \pm 111950 0 ^{2} + 3.59511 E 13}{2 \cdot 56526}

将解分隔开

x_{1} = \frac{- ( - 1119500 ) + 111950 0 ^{2} + 3.59511 E 13}{2 \cdot 56526}, x_{2} = \frac{- ( - 1119500 ) - 111950 0 ^{2} + 3.59511 E 13}{2 \cdot 56526}

x = \frac{- ( - 1119500 ) + 111950 0 ^{2} + 3.59511 E 13}{2 \cdot 56526} : \frac{1119500 + 111950 0 ^{2} + 3.59511 E 13}{113052}

x = \frac{- ( - 1119500 ) - 111950 0 ^{2} + 3.59511 E 13}{2 \cdot 56526} : \frac{1119500 - 111950 0 ^{2} + 3.59511 E 13}{113052}

二次方程组的解是:

x = \frac{1119500 + 111950 0 ^{2} + 3.59511 E 13}{113052}, x = \frac{1119500 - 111950 0 ^{2} + 3.59511 E 13}{113052}
