solvefor x,r(x)^2=(0.998-0.954x)/(213879)

解

解く

x, r (x)^{2} = \frac{0.998 - 0.954 x}{213879}

解

x = \frac{- 0.954 + 0.910116 + 853804.968 r}{427758 r}, x = \frac{- 0.954 - 0.910116 + 853804.968 r}{427758 r}; r \neq = 0

解答ステップ

r x^{2} = \frac{0.998 - 0.954 x}{213879}

以下で両辺を乗じる:

213879

213879 x^{2} r = 0.998 - 0.954 x

0.954 x

を左側に移動します

213879 x^{2} r + 0.954 x = 0.998

0.998

を左側に移動します

213879 x^{2} r + 0.954 x - 0.998 = 0

標準的な形式で書く

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

213879 r x^{2} + 0.954 x - 0.998 = 0

解くとthe二次式

x_{1, 2} = \frac{- 0.954 \pm 0.95 4 ^{2} - 4 \cdot 213879 r ( - 0.998 )}{2 \cdot 213879 r}

簡素化

0.95 4^{2} - 4 \cdot 213879 r (- 0.998) : 0.910116 + 853804.968 r

x_{1, 2} = \frac{- 0.954 \pm 0.910116 + 853804.968 r}{2 \cdot 213879 r}; r \neq = 0

解を分離する

x_{1} = \frac{- 0.954 + 0.910116 + 853804.968 r}{2 \cdot 213879 r}, x_{2} = \frac{- 0.954 - 0.910116 + 853804.968 r}{2 \cdot 213879 r}

x = \frac{- 0.954 + 0.910116 + 853804.968 r}{2 \cdot 213879 r} : \frac{- 0.954 + 0.910116 + 853804.968 r}{427758 r}

x = \frac{- 0.954 - 0.910116 + 853804.968 r}{2 \cdot 213879 r} : \frac{- 0.954 - 0.910116 + 853804.968 r}{427758 r}

二次equationの解:

x = \frac{- 0.954 + 0.910116 + 853804.968 r}{427758 r}, x = \frac{- 0.954 - 0.910116 + 853804.968 r}{427758 r}; r \neq = 0

(f(x)(f(x)+x))/(f(x))=x^2+1776x+2010

\frac{f ( x ) ( f ( x ) + x )}{f ( x )} = x^{2} + 1776 x + 2010

2 x^{2} + 3 x > y - 2

x^{2} - 8 x - 4 y + 20 = 0

(y + 6)^{2} = 4 (x + 5)

y^{2} - 4 y = 3 x - 6
