-49p^2=7

解答

- 49 p^{2} = 7

解答

p = \frac{1}{7} i, p = - \frac{1}{7} i

求解步骤

- 49 p^{2} = 7

两边除以

- 49

p^{2} = - \frac{1}{7}

对于

x^{2} = f (a)

解为

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

p = - \frac{1}{7}, p = - - \frac{1}{7}

- \frac{1}{7} = \frac{1}{7} i

- - \frac{1}{7} = - \frac{1}{7} i

p = \frac{1}{7} i, p = - \frac{1}{7} i

流行的例子

- 2 x + x^{2} + \frac{3}{4} = 0

3 x^{2} - 4 x = 20 x + 27

k=r^2+5,6<= r<= 7

k = r^{2} + 5, 6 \leq r \leq 7

1 x^{2} + 7 x + 15 = 0

x^2+3x-24=3x+13x+1

x^{2} + 3 x - 24 = 3 x + 13 x + 1
