1/2 x^2-50=0

解答

\frac{1}{2} x^{2} - 50 = 0

解答

x = 10, x = - 10

求解步骤

\frac{1}{2} x^{2} - 50 = 0

将

50

到右边

\frac{1}{2} x^{2} = 50

在两边乘以

2

x^{2} = 100

对于

x^{2} = f (a)

解为

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

x = 100, x = - 100

100 = 10

- 100 = - 10

x = 10, x = - 10

n^{2} + 4 n - 5 = 0

4+x/2-(x^2)/8 =0

4 + \frac{x}{2} - \frac{x ^{2}}{8} = 0

3 x^{2} - 16 x - 35 = 0

(k-1)x^2+2x+(2k-3)=0

(k - 1) x^{2} + 2 x + (2 k - 3) = 0
