solvefor y,x^2-y^2=0

解答

求解

y, x^{2} - y^{2} = 0

解答

y = x, y = - x

求解步骤

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

将

x^{2}

到右边

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

两边除以

- 1

y^{2} = x^{2}

对于

x^{2} = f (a)

解为

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

y = x^{2}, y = - x^{2}

化简

x^{2} : x

化简

- x^{2} : - x

y = x, y = - x

流行的例子

25x^2+9y^2-100x+18y-116=0

25 x^{2} + 9 y^{2} - 100 x + 18 y - 116 = 0

(x-1)^2+(y-2)^2=4

(x - 1)^{2} + (y - 2)^{2} = 4

准线 y^2=-36x

d i rec t r i x y^{2} = - 36 x

x^{2} + 4 y^{2} = 36

solvefor y,x^2-6x+9-4y^2=0

so l v e f or y, x^{2} - 6 x + 9 - 4 y^{2} = 0
