10x^2+1=0

解答

10 x^{2} + 1 = 0

解答

x = \frac{1}{10} i, x = - \frac{1}{10} i

求解步骤

10 x^{2} + 1 = 0

将

1

到右边

10 x^{2} = - 1

两边除以

10

x^{2} = - \frac{1}{10}

对于

x^{2} = f (a)

解为

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

x = - \frac{1}{10}, x = - - \frac{1}{10}

- \frac{1}{10} = \frac{1}{10} i

- - \frac{1}{10} = - \frac{1}{10} i

x = \frac{1}{10} i, x = - \frac{1}{10} i

x (x + 36) = 5152

x^{2} = 7^{2} + 5^{2}

2 X^{2} - X + 3 = 0

solvefor x,x^2+y^2-2hx=0

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

n^{2} - 3 n - 18 = 0
