solvefor x,3x^2-6Y(x)^2-36=0

解答

求解

x, 3 x^{2} - 6 Y (x)^{2} - 36 = 0

解答

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

求解步骤

3 x^{2} - 6 Y x^{2} - 36 = 0

将

36

到右边

3 x^{2} - 6 Y x^{2} = 36

分解

3 x^{2} - 6 Y x^{2} : 3 x^{2} (1 - 2 Y)

3 x^{2} (1 - 2 Y) = 36

两边除以

3 (1 - 2 Y); Y \neq = \frac{1}{2}

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

对于

x^{2} = f (a)

解为

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

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

化简

\frac{12}{1 - 2 Y} : \frac{2 3}{1 - 2 Y}

化简

- \frac{12}{1 - 2 Y} : - \frac{2 3}{1 - 2 Y}

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

流行的例子

(y^2)/2+y=(x^2)/2-x+21/32

\frac{y ^{2}}{2} + y = \frac{x ^{2}}{2} - x + \frac{21}{32}

(y^2)/3-(x^2)/1 =1

\frac{y ^{2}}{3} - \frac{x ^{2}}{1} = 1

3x^2-y^2-24x-8y+61=0

3 x^{2} - y^{2} - 24 x - 8 y + 61 = 0

(y + 2)^{2} = 2 x^{2} + 8

((y-8)^2)/(25)-((x-12)^2)/(16)=1

\frac{( y - 8 ) ^{2}}{25} - \frac{( x - 12 ) ^{2}}{16} = 1
