solvefor x,x^2-3x^2y=C

解答

求解

x, x^{2} - 3 x^{2} y = C

解答

x = \frac{C}{1 - 3 y}, x = - \frac{C}{1 - 3 y}; y \neq = \frac{1}{3}

求解步骤

x^{2} - 3 x^{2} y = C

分解

x^{2} - 3 x^{2} y : x^{2} (1 - 3 y)

x^{2} (1 - 3 y) = C

两边除以

1 - 3 y; y \neq = \frac{1}{3}

x^{2} = \frac{C}{1 - 3 y}; y \neq = \frac{1}{3}

对于

x^{2} = f (a)

解为

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

x = \frac{C}{1 - 3 y}, x = - \frac{C}{1 - 3 y}; y \neq = \frac{1}{3}

3 k^{2} - 96 k + 92 = 0

(2x+10)(3x-15)=0

(2 x + 10) (3 x - 15) = 0

12 x^{2} - 2 = 8 x

(81+k(k+1))/2 =127

\frac{81 + k ( k + 1 )}{2} = 127

2 x^{2} - 5 = 7 x
