36x^2=1

解答

36 x^{2} = 1

解答

x = \frac{1}{6}, x = - \frac{1}{6}

+1

十进制

x = 0.16666 \dots, x = - 0.16666 \dots

求解步骤

36 x^{2} = 1

两边除以

36

x^{2} = \frac{1}{36}

对于

x^{2} = f (a)

解为

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

x = \frac{1}{36}, x = - \frac{1}{36}

\frac{1}{36} = \frac{1}{6}

- \frac{1}{36} = - \frac{1}{6}

x = \frac{1}{6}, x = - \frac{1}{6}

(3 x + 5)^{2} = 10

(2 n + 3)^{2} = 4

(x) = 4 x^{2} - 3 x + 25

9x^2-5x((28x)/(33))+7((28x)/(33))^2=120

9 x^{2} - 5 x (\frac{28 x}{33}) + 7 (\frac{28 x}{33})^{2} = 120

(x^2-4x+4)-((20x+8)^2)/(225)=4

(x^{2} - 4 x + 4) - \frac{( 20 x + 8 ) ^{2}}{225} = 4
