solvefor x,x^2(y^2-4)=4

解答

求解

x, x^{2} (y^{2} - 4) = 4

解答

x = \frac{2}{y ^{2} - 4}, x = - \frac{2}{y ^{2} - 4}; y \neq = 2, y \neq = - 2

求解步骤

x^{2} (y^{2} - 4) = 4

两边除以

y^{2} - 4; y \neq = 2, y \neq = - 2

x^{2} = \frac{4}{y ^{2} - 4}; y \neq = 2, y \neq = - 2

对于

x^{2} = f (a)

解为

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

x = \frac{4}{y ^{2} - 4}, x = - \frac{4}{y ^{2} - 4}; y \neq = 2, y \neq = - 2

化简

\frac{4}{y ^{2} - 4} : \frac{2}{y ^{2} - 4}

化简

- \frac{4}{y ^{2} - 4} : - \frac{2}{y ^{2} - 4}

x = \frac{2}{y ^{2} - 4}, x = - \frac{2}{y ^{2} - 4}; y \neq = 2, y \neq = - 2

solvefor x,4y^2+10x^2-2y+5=0

so l v e f or x, 4 y^{2} + 10 x^{2} - 2 y + 5 = 0

2 x^{2} + 5 x = 8

x^{2} - 5 x = 84

(x+3)^2+(x-6)(x+5)=0

(x + 3)^{2} + (x - 6) (x + 5) = 0

25t-0.05t^2=15t+200

25 t - 0.05 t^{2} = 15 t + 200
