(37.15-1x)*(10.19-0.5x)-(15.12)^2=0

解

(37.15 - 1 x) \cdot (10.19 - 0.5 x) - (15.12)^{2} = 0

解

x = 28.765 + 527.537025, x = 28.765 - 527.537025

+1

十進法表記

x = 51.73317 \dots, x = 5.79682 \dots

解答ステップ

(37.15 - 1 \cdot x) (10.19 - 0.5 x) - (15.12)^{2} = 0

拡張

(37.15 - 1 \cdot x) (10.19 - 0.5 x) - 15.1 2^{2} : 0.5 x^{2} - 28.765 x + 149.9441

0.5 x^{2} - 28.765 x + 149.9441 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 28.765 ) \pm ( - 28.765 ) ^{2} - 4 \cdot 0.5 \cdot 149.9441}{2 \cdot 0.5}

(- 28.765)^{2} - 4 \cdot 0.5 \cdot 149.9441 = 527.537025

x_{1, 2} = \frac{- ( - 28.765 ) \pm 527.537025}{2 \cdot 0.5}

解を分離する

x_{1} = \frac{- ( - 28.765 ) + 527.537025}{2 \cdot 0.5}, x_{2} = \frac{- ( - 28.765 ) - 527.537025}{2 \cdot 0.5}

x = \frac{- ( - 28.765 ) + 527.537025}{2 \cdot 0.5} : 28.765 + 527.537025

x = \frac{- ( - 28.765 ) - 527.537025}{2 \cdot 0.5} : 28.765 - 527.537025

二次equationの解:

x = 28.765 + 527.537025, x = 28.765 - 527.537025
