-x^2=3

解答

- x^{2} = 3

解答

x = 3 i, x = - 3 i

求解步骤

- x^{2} = 3

两边除以

- 1

x^{2} = - 3

对于

x^{2} = f (a)

解为

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

x = - 3, x = - - 3

- 3 = 3 i

- - 3 = - 3 i

x = 3 i, x = - 3 i

solvefor p,2(p-q)^2-(p-q)-1=0

so l v e f or p, 2 (p - q)^{2} - (p - q) - 1 = 0

m^{2} + m - 56 = 0

m^{2} - 9 m + 20 = 0

z - z^{2} - \frac{1}{8} = 0

solvefor x,x^2-36=0

so l v e f or x, x^{2} - 36 = 0
