solvefor x,(x^2)/4+1=3m(x)^2-1

解答

求解

x, \frac{x ^{2}}{4} + 1 = 3 m (x)^{2} - 1

解答

x = i \frac{2 2 1 - 12 m}{1 - 12 m}, x = - i \frac{2 2 1 - 12 m}{1 - 12 m}; m \neq = \frac{1}{12}

求解步骤

\frac{x ^{2}}{4} + 1 = 3 m x^{2} - 1

将

1

到右边

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

将

3 m x^{2}

para o lado esquerdo

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

在两边乘以

4

x^{2} - 12 m x^{2} = - 8

分解

x^{2} - 12 m x^{2} : x^{2} (1 - 12 m)

x^{2} (1 - 12 m) = - 8

两边除以

1 - 12 m; m \neq = \frac{1}{12}

x^{2} = - \frac{8}{1 - 12 m}; m \neq = \frac{1}{12}

对于

x^{2} = f (a)

解为

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

x = - \frac{8}{1 - 12 m}, x = - - \frac{8}{1 - 12 m}; m \neq = \frac{1}{12}

化简

- \frac{8}{1 - 12 m} : i \frac{2 2 1 - 12 m}{1 - 12 m}

化简

- - \frac{8}{1 - 12 m} : - i \frac{2 2 1 - 12 m}{1 - 12 m}

x = i \frac{2 2 1 - 12 m}{1 - 12 m}, x = - i \frac{2 2 1 - 12 m}{1 - 12 m}; m \neq = \frac{1}{12}

流行的例子

((x-1)^2)/9-((y-2)^2)/4 =1

\frac{( x - 1 ) ^{2}}{9} - \frac{( y - 2 ) ^{2}}{4} = 1

(((x+1))/(16))^2-(((y-4))/(25))^2=1

(\frac{( x + 1 )}{16})^{2} - (\frac{( y - 4 )}{25})^{2} = 1

x^2-4y^2-4x-12=0

x^{2} - 4 y^{2} - 4 x - 12 = 0

x^2-y^2+2x-5y+10=0

x^{2} - y^{2} + 2 x - 5 y + 10 = 0

-8x^2+y^2-36x+6y-27=0

- 8 x^{2} + y^{2} - 36 x + 6 y - 27 = 0
