(9 x + 3)^{2} = 11

解答

x = \frac{11 - 3}{9}, x = \frac{- 11 - 3}{9}

+1

十进制

x = 0.03518 \dots, x = - 0.70184 \dots

求解步骤

(9 x + 3)^{2} = 11

对于

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

解为

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

解

9 x + 3 = 11 : x = \frac{11 - 3}{9}

解

9 x + 3 = - 11 : x = \frac{- 11 - 3}{9}

二次方程组的解是:

x = \frac{11 - 3}{9}, x = \frac{- 11 - 3}{9}
