36x^2+25=0

解答

36 x^{2} + 25 = 0

解答

x = \frac{5}{6} i, x = - \frac{5}{6} i

求解步骤

36 x^{2} + 25 = 0

将

25

到右边

36 x^{2} = - 25

两边除以

36

x^{2} = - \frac{25}{36}

对于

x^{2} = f (a)

解为

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

x = - \frac{25}{36}, x = - - \frac{25}{36}

- \frac{25}{36} = \frac{5}{6} i

- - \frac{25}{36} = - \frac{5}{6} i

x = \frac{5}{6} i, x = - \frac{5}{6} i

x^{2} - 10 x = - 9

4 a^{2} + 2 a + 2 = 5

5(x^2-7)=3(4+x^2)+5

5 (x^{2} - 7) = 3 (4 + x^{2}) + 5

(- 2 x + 3)^{2} = 9

5 x - 7 x^{2} = 3 x + 4
