(6x+3)^2=8

解

(6 x + 3)^{2} = 8

解

x = \frac{2 2 - 3}{6}, x = \frac{- 2 2 - 3}{6}

+1

十進法表記

x = - 0.02859 \dots, x = - 0.97140 \dots

解答ステップ

(6 x + 3)^{2} = 8

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

の場合, 解は

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

解く

6 x + 3 = 8 : x = \frac{2 2 - 3}{6}

解く

6 x + 3 = - 8 : x = \frac{- 2 2 - 3}{6}

二次equationの解:

x = \frac{2 2 - 3}{6}, x = \frac{- 2 2 - 3}{6}
