solvefor x,8x^2+9y^2+288=0

解答

求解

x, 8 x^{2} + 9 y^{2} + 288 = 0

解答

x = \frac{3 - y ^{2} - 32}{2 2}, x = - \frac{3 - y ^{2} - 32}{2 2}

求解步骤

8 x^{2} + 9 y^{2} + 288 = 0

将

9 y^{2}

到右边

8 x^{2} + 288 = - 9 y^{2}

将

288

到右边

8 x^{2} = - 9 y^{2} - 288

两边除以

8

x^{2} = \frac{- 9 y ^{2} - 288}{8}

对于

x^{2} = f (a)

解为

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

x = \frac{- 9 y ^{2} - 288}{8}, x = - \frac{- 9 y ^{2} - 288}{8}

化简

\frac{- 9 y ^{2} - 288}{8} : \frac{3 - y ^{2} - 32}{2 2}

化简

- \frac{- 9 y ^{2} - 288}{8} : - \frac{3 - y ^{2} - 32}{2 2}

x = \frac{3 - y ^{2} - 32}{2 2}, x = - \frac{3 - y ^{2} - 32}{2 2}

流行的例子

x^{2} - 2 x + 2 = 2 x

12 x^{2} = 3 x

e^{2} + 6 e + 12 = 0

- X (2 X - 1) = 0

120 x^{2} + x = 75
