(2x+3)^2=-4

解答

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

解答

x = - \frac{3}{2} + i, x = - \frac{3}{2} - i

求解步骤

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

对于

(g (x))^{2} = f (a)

解为

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

解

2 x + 3 = - 4 : x = - \frac{3}{2} + i

解

2 x + 3 = - - 4 : x = - \frac{3}{2} - i

二次方程组的解是:

x = - \frac{3}{2} + i, x = - \frac{3}{2} - i
