(12x-27)^2=256

解答

(12 x - 27)^{2} = 256

解答

x = \frac{43}{12}, x = \frac{11}{12}

+1

十进制

x = 3.58333 \dots, x = 0.91666 \dots

求解步骤

(12 x - 27)^{2} = 256

对于

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

解为

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

解

12 x - 27 = 256 : x = \frac{43}{12}

解

12 x - 27 = - 256 : x = \frac{11}{12}

二次方程组的解是:

x = \frac{43}{12}, x = \frac{11}{12}
