solvefor x,4x^2+9y^2-36z=0

解答

求解

x, 4 x^{2} + 9 y^{2} - 36 z = 0

解答

x = \frac{3 - y ^{2} + 4 z}{2}, x = - \frac{3 - y ^{2} + 4 z}{2}

求解步骤

4 x^{2} + 9 y^{2} - 36 z = 0

将

9 y^{2}

到右边

4 x^{2} - 36 z = - 9 y^{2}

将

36 z

到右边

4 x^{2} = - 9 y^{2} + 36 z

两边除以

4

x^{2} = \frac{- 9 y ^{2} + 36 z}{4}

对于

x^{2} = f (a)

解为

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

x = \frac{- 9 y ^{2} + 36 z}{4}, x = - \frac{- 9 y ^{2} + 36 z}{4}

化简

\frac{- 9 y ^{2} + 36 z}{4} : \frac{3 - y ^{2} + 4 z}{2}

化简

- \frac{- 9 y ^{2} + 36 z}{4} : - \frac{3 - y ^{2} + 4 z}{2}

x = \frac{3 - y ^{2} + 4 z}{2}, x = - \frac{3 - y ^{2} + 4 z}{2}
