2=-35(2x/(-0.00796)-(x/(-0.00796))^2)

해법

2 = - 35 \cdot (2 \cdot \frac{x}{- 0.00796} - (\frac{x}{- 0.00796})^{2})

해법

x = \frac{- 0.004435312 + 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}, x = \frac{- 0.004435312 - 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}

2 = - 35 (2 \cdot \frac{x}{- 0.00796} - (\frac{x}{- 0.00796})^{2})

- 35 (2 \cdot \frac{x}{- 0.00796} - (\frac{x}{- 0.00796})^{2})

확장 :

\frac{70 x}{0.00796} + \frac{35 x ^{2}}{0.0000633616}

2 = \frac{70 x}{0.00796} + \frac{35 x ^{2}}{0.0000633616}

측면 전환

\frac{70 x}{0.00796} + \frac{35 x ^{2}}{0.0000633616} = 2

표준 양식으로 작성

a x^{2} + b x + c = 0

x^{2} + \frac{0.004435312 x}{0.2786} - \frac{1.00872 E - 6}{0.2786} = 0

쿼드 공식으로 해결

x_{1, 2} = \frac{- \frac{0.004435312}{0.2786} \pm ( \frac{0.004435312}{0.2786} ) ^{2} - 4 \cdot 1 \cdot ( - \frac{1.00872 E - 6}{0.2786} )}{2 \cdot 1}

(\frac{0.004435312}{0.2786})^{2} - 4 \cdot 1 \cdot (- \frac{1.00872 E - 6}{0.2786}) = \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}

x_{1, 2} = \frac{- \frac{0.004435312}{0.2786} \pm \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{2 \cdot 1}
