8x^2=-7n+8

解答

8 x^{2} = - 7 n + 8

解答

x = \frac{- 7 n + 8}{2 2}, x = - \frac{- 7 n + 8}{2 2}

求解步骤

8 x^{2} = - 7 n + 8

两边除以

8

x^{2} = \frac{- 7 n + 8}{8}

对于

x^{2} = f (a)

解为

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

x = \frac{- 7 n + 8}{8}, x = - \frac{- 7 n + 8}{8}

化简

\frac{- 7 n + 8}{8} : \frac{- 7 n + 8}{2 2}

化简

- \frac{- 7 n + 8}{8} : - \frac{- 7 n + 8}{2 2}

x = \frac{- 7 n + 8}{2 2}, x = - \frac{- 7 n + 8}{2 2}
