solvefor x,x^3+y^2=1

解答

求解

x, x^{3} + y^{2} = 1

解答

x = 3 1 - y^{2}, x = - \frac{3 1 - y ^{2}}{2} + \frac{3 1 - y ^{2} 3}{2} i, x = - \frac{3 1 - y ^{2}}{2} - \frac{3 1 - y ^{2} 3}{2} i

求解步骤

x^{3} + y^{2} = 1

将

y^{2}

到右边

x^{3} = 1 - y^{2}

对于

x^{3} = f (a)

解为

x = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

x = 3 1 - y^{2}, x = 3 1 - y^{2} \frac{- 1 + 3 i}{2}, x = 3 1 - y^{2} \frac{- 1 - 3 i}{2}

化简

3 1 - y^{2} \frac{- 1 + 3 i}{2} : - \frac{3 1 - y ^{2}}{2} + \frac{3 1 - y ^{2} 3}{2} i

化简

3 1 - y^{2} \frac{- 1 - 3 i}{2} : - \frac{3 1 - y ^{2}}{2} - \frac{3 1 - y ^{2} 3}{2} i

x = 3 1 - y^{2}, x = - \frac{3 1 - y ^{2}}{2} + \frac{3 1 - y ^{2} 3}{2} i, x = - \frac{3 1 - y ^{2}}{2} - \frac{3 1 - y ^{2} 3}{2} i

(1-y)(3-y)(6-y)=18

(1 - y) (3 - y) (6 - y) = 18

(s^3-s^2+s-1)=s^2+3s+4

(s^{3} - s^{2} + s - 1) = s^{2} + 3 s + 4

8 x^{4} = 6 x^{3}

x^3+7x^2+2x+14=0

x^{3} + 7 x^{2} + 2 x + 14 = 0

x^4-16x^3+76x^2-96x+16=0

x^{4} - 16 x^{3} + 76 x^{2} - 96 x + 16 = 0
