3x^2= 3/4

解答

3 x^{2} = \frac{3}{4}

x = \frac{1}{2}, x = - \frac{1}{2}

十进制

x = 0.5, x = - 0.5

求解步骤

3 x^{2} = \frac{3}{4}

两边除以

3

x^{2} = \frac{1}{4}

对于

x^{2} = f (a)

解为

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

x = \frac{1}{4}, x = - \frac{1}{4}

\frac{1}{4} = \frac{1}{2}

- \frac{1}{4} = - \frac{1}{2}

x = \frac{1}{2}, x = - \frac{1}{2}
