solvefor x,z^2=x^2y+4.02

解答

求解

x, z^{2} = x^{2} y + 4.02

解答

x = \frac{z ^{2} - 4.02}{y}, x = - \frac{z ^{2} - 4.02}{y}; y \neq = 0

求解步骤

z^{2} = x^{2} y + 4.02

交换两边

x^{2} y + 4.02 = z^{2}

将

4.02

到右边

x^{2} y = z^{2} - 4.02

两边除以

y; y \neq = 0

x^{2} = \frac{z ^{2} - 4.02}{y}; y \neq = 0

对于

x^{2} = f (a)

解为

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

x = \frac{z ^{2} - 4.02}{y}, x = - \frac{z ^{2} - 4.02}{y}; y \neq = 0
