9r^2-3=-152

解答

9 r^{2} - 3 = - 152

解答

r = \frac{149}{3} i, r = - \frac{149}{3} i

求解步骤

9 r^{2} - 3 = - 152

将

3

到右边

9 r^{2} = - 149

两边除以

9

r^{2} = - \frac{149}{9}

对于

x^{2} = f (a)

解为

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

r = - \frac{149}{9}, r = - - \frac{149}{9}

- \frac{149}{9} = \frac{149}{3} i

- - \frac{149}{9} = - \frac{149}{3} i

r = \frac{149}{3} i, r = - \frac{149}{3} i
