-6x^2=72

解答

- 6 x^{2} = 72

解答

x = 23 i, x = - 23 i

求解步骤

- 6 x^{2} = 72

两边除以

- 6

x^{2} = - 12

对于

x^{2} = f (a)

解为

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

x = - 12, x = - - 12

- 12 = 23 i

- - 12 = - 23 i

x = 23 i, x = - 23 i

c^{2} + c - 19 = 4 c

- x^{2} + 6 x = 10

x^2-11/10 x+1/10 =0

x^{2} - \frac{11}{10} x + \frac{1}{10} = 0

2 x^{2} - 9 x + 13 = 0

5 x^{2} + 7 = - 60
