solvefor x,2y^2+3x^2=1

解答

求解

x, 2 y^{2} + 3 x^{2} = 1

解答

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

求解步骤

2 y^{2} + 3 x^{2} = 1

将

2 y^{2}

到右边

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

两边除以

3

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

对于

x^{2} = f (a)

解为

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

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