solvefor x,13x^2+2x^2y=1

解答

求解

x, 13 x^{2} + 2 x^{2} y = 1

解答

x = \frac{1}{13 + 2 y}, x = - \frac{1}{13 + 2 y}; y \neq = - \frac{13}{2}

求解步骤

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

分解

13 x^{2} + 2 x^{2} y : x^{2} (13 + 2 y)

x^{2} (13 + 2 y) = 1

两边除以

13 + 2 y; y \neq = - \frac{13}{2}

x^{2} = \frac{1}{13 + 2 y}; y \neq = - \frac{13}{2}

对于

x^{2} = f (a)

解为

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

x = \frac{1}{13 + 2 y}, x = - \frac{1}{13 + 2 y}; y \neq = - \frac{13}{2}

化简

\frac{1}{13 + 2 y} : \frac{1}{13 + 2 y}

化简

- \frac{1}{13 + 2 y} : - \frac{1}{13 + 2 y}

x = \frac{1}{13 + 2 y}, x = - \frac{1}{13 + 2 y}; y \neq = - \frac{13}{2}

solvefor a,e^2+f^2=2(a^2+b^2)

so l v e f or a, e^{2} + f^{2} = 2 (a^{2} + b^{2})

solvefor x,(x^2)/3+(y^2)/3 =(a^2)/3

so l v e f or x, \frac{x ^{2}}{3} + \frac{y ^{2}}{3} = \frac{a ^{2}}{3}

solvefor x,f(x^2+x)=x+2x

so l v e f or x, f (x^{2} + x) = x + 2 x

5.5 + b^{2} = 6

x^{2} - 30 x = 20
