solvefor c,8c^2xy=(x^2-y^2)^2

解答

求解

c, 8 c^{2} x y = (x^{2} - y^{2})^{2}

解答

c = \frac{x ^{2} - y ^{2}}{2 2 x y}, c = - \frac{x ^{2} - y ^{2}}{2 2 x y}; 8 x y \neq = 0

求解步骤

8 c^{2} x y = (x^{2} - y^{2})^{2}

两边除以

8 x y; 8 x y \neq = 0

c^{2} = \frac{( x ^{2} - y ^{2} ) ^{2}}{8 x y}; 8 x y \neq = 0

对于

x^{2} = f (a)

解为

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

c = \frac{( x ^{2} - y ^{2} ) ^{2}}{8 x y}, c = - \frac{( x ^{2} - y ^{2} ) ^{2}}{8 x y}; 8 x y \neq = 0

化简

\frac{( x ^{2} - y ^{2} ) ^{2}}{8 x y} : \frac{x ^{2} - y ^{2}}{2 2 x y}

化简

- \frac{( x ^{2} - y ^{2} ) ^{2}}{8 x y} : - \frac{x ^{2} - y ^{2}}{2 2 x y}

c = \frac{x ^{2} - y ^{2}}{2 2 x y}, c = - \frac{x ^{2} - y ^{2}}{2 2 x y}; 8 x y \neq = 0
