(3x-2)^2=9

解答

(3 x - 2)^{2} = 9

解答

x = \frac{5}{3}, x = - \frac{1}{3}

+1

十进制

x = 1.66666 \dots, x = - 0.33333 \dots

求解步骤

(3 x - 2)^{2} = 9

对于

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

解为

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

解

3 x - 2 = 9 : x = \frac{5}{3}

解

3 x - 2 = - 9 : x = - \frac{1}{3}

二次方程组的解是:

x = \frac{5}{3}, x = - \frac{1}{3}

0.3 x^{2} + x - 40 = 0

(x+4)^2+11(x+4)+30=0

(x + 4)^{2} + 11 (x + 4) + 30 = 0

0 = - 16 t^{2} + 8 t + 12

(8 x + 7) (x - 6) = 0

24 x^{2} - 14 x = 0
