solvefor x,3m(x)^2-2x^2-1=0

解答

求解

x, 3 m (x)^{2} - 2 x^{2} - 1 = 0

解答

x = \frac{1}{3 m - 2}, x = - \frac{1}{3 m - 2}; m \neq = \frac{2}{3}

求解步骤

3 m x^{2} - 2 x^{2} - 1 = 0

将

1

到右边

3 m x^{2} - 2 x^{2} = 1

分解

3 m x^{2} - 2 x^{2} : x^{2} (3 m - 2)

x^{2} (3 m - 2) = 1

两边除以

3 m - 2; m \neq = \frac{2}{3}

x^{2} = \frac{1}{3 m - 2}; m \neq = \frac{2}{3}

对于

x^{2} = f (a)

解为

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

x = \frac{1}{3 m - 2}, x = - \frac{1}{3 m - 2}; m \neq = \frac{2}{3}

化简

\frac{1}{3 m - 2} : \frac{1}{3 m - 2}

化简

- \frac{1}{3 m - 2} : - \frac{1}{3 m - 2}

x = \frac{1}{3 m - 2}, x = - \frac{1}{3 m - 2}; m \neq = \frac{2}{3}

流行的例子

5 x^{2} - 4 y^{2} - 80 = 0

y + y^{2} = x^{2} + 4

y + y^{2} = x^{2} + 6

x^2-y^2=x-y+2018

x^{2} - y^{2} = x - y + 2018

((x-1)^2)/(64)-((y-7)^2)/(64)=1

\frac{( x - 1 ) ^{2}}{64} - \frac{( y - 7 ) ^{2}}{64} = 1
