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

解答

求解

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

解答

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

求解步骤

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

交换两边

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

将

y^{2}

到右边

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

对于

x^{2} = f (a)

解为

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

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

流行的例子

12 x^{2} = 72 x

(3x-1)^2-49=-13

(3 x - 1)^{2} - 49 = - 13

3 x^{2} + 8 x - 5 = 0

2x^2+(4a-b)x-2ab=0

2 x^{2} + (4 a - b) x - 2 ab = 0

因式分解 2x^2-5x-3=0

f a c t or 2 x^{2} - 5 x - 3 = 0
