0.44048x^2-60.726x+1848.6=0

解

0.44048 x^{2} - 60.726 x + 1848.6 = 0

x = \frac{60.726 + 430.561764}{0.88096}, x = \frac{60.726 - 430.561764}{0.88096}

十進法表記

x = 92.48545 \dots, x = 45.37778 \dots

解答ステップ

0.44048 x^{2} - 60.726 x + 1848.6 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 60.726 ) \pm ( - 60.726 ) ^{2} - 4 \cdot 0.44048 \cdot 1848.6}{2 \cdot 0.44048}

(- 60.726)^{2} - 4 \cdot 0.44048 \cdot 1848.6 = 430.561764

x_{1, 2} = \frac{- ( - 60.726 ) \pm 430.561764}{2 \cdot 0.44048}

解を分離する

x_{1} = \frac{- ( - 60.726 ) + 430.561764}{2 \cdot 0.44048}, x_{2} = \frac{- ( - 60.726 ) - 430.561764}{2 \cdot 0.44048}

x = \frac{- ( - 60.726 ) + 430.561764}{2 \cdot 0.44048} : \frac{60.726 + 430.561764}{0.88096}

x = \frac{- ( - 60.726 ) - 430.561764}{2 \cdot 0.44048} : \frac{60.726 - 430.561764}{0.88096}

二次equationの解:

x = \frac{60.726 + 430.561764}{0.88096}, x = \frac{60.726 - 430.561764}{0.88096}
