solvefor y,x^3=(y-x^2)^2

解答

求解

y, x^{3} = (y - x^{2})^{2}

解答

y = x x + x^{2}, y = - x x + x^{2}

求解步骤

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

交换两边

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

对于

(g (x))^{2} = f (a)

解为

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

解

y - x^{2} = x^{3} : y = x x + x^{2}

解

y - x^{2} = - x^{3} : y = - x x + x^{2}

二次方程组的解是:

y = x x + x^{2}, y = - x x + x^{2}

流行的例子

x^{2} - x = 156

x^{2} + 6 x + 4 x + 24 = 0

3 x^{2} = x + 3

v(v+1)=3v^2+18/4

v (v + 1) = 3 v^{2} + \frac{18}{4}

solvefor x,36x^2-12x+1=k^2

so l v e f or x, 36 x^{2} - 12 x + 1 = k^{2}
