(5x-2)^2=10

解答

(5 x - 2)^{2} = 10

解答

x = \frac{10 + 2}{5}, x = \frac{- 10 + 2}{5}

+1

十进制

x = 1.03245 \dots, x = - 0.23245 \dots

求解步骤

(5 x - 2)^{2} = 10

对于

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

解为

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

解

5 x - 2 = 10 : x = \frac{10 + 2}{5}

解

5 x - 2 = - 10 : x = \frac{- 10 + 2}{5}

二次方程组的解是:

x = \frac{10 + 2}{5}, x = \frac{- 10 + 2}{5}

j o in 2 π - \frac{5 π}{3}

(|6-5x|)/(|x+3|)<= 1/2

\frac{∣ 6 - 5 x ∣}{∣ x + 3 ∣} \leq \frac{1}{2}
