solvefor x,-x^2-3y^3=5

解答

求解

x, - x^{2} - 3 y^{3} = 5

解答

x = - 5 - 3 y^{3}, x = - - 5 - 3 y^{3}

求解步骤

- x^{2} - 3 y^{3} = 5

将

3 y^{3}

到右边

- x^{2} = 5 + 3 y^{3}

两边除以

- 1

x^{2} = - 5 - 3 y^{3}

对于

x^{2} = f (a)

解为

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

x = - 5 - 3 y^{3}, x = - - 5 - 3 y^{3}

2 x^{2} = 20 - 3 x^{2}

solvefor x,x^2+8x-2=0

so l v e f or x, x^{2} + 8 x - 2 = 0

x^{2} + 18 x + 63 = 0

3(3x+2)-6x-5=4x^2

3 (3 x + 2) - 6 x - 5 = 4 x^{2}

x^{2} - 116 = 0
