3/1000 = 1/2 (0.005)(x-3-0.5)^2

解

\frac{3}{1000} = \frac{1}{2} (0.005) (x - 3 - 0.5)^{2}

解

x = 4.59544 \dots, x = 2.40455 \dots

解答ステップ

\frac{3}{1000} = \frac{1}{2} (0.005) (x - 3 - 0.5)^{2}

辺を交換する

\frac{1}{2} (0.005) (x - 3 - 0.5)^{2} = \frac{3}{1000}

簡素化

\frac{1}{2} (0.005) : \frac{0.005}{2}

\frac{0.005}{2} (x - 3 - 0.5)^{2} = \frac{3}{1000}

以下で両辺を乗じる:

2

0.005 (x - 3 - 0.5)^{2} = \frac{3}{500}

以下で両辺を割る

0.005

(x - 3 - 0.5)^{2} = 1.2

(g (x))^{2} = f (a)

の場合, 解は

g (x) = f (a), - f (a)

解く

x - 3 - 0.5 = 1.2 : x = 4.59544 \dots

解く

x - 3 - 0.5 = - 1.2 : x = 2.40455 \dots

二次equationの解:

x = 4.59544 \dots, x = 2.40455 \dots
