Assignment:Find the solution set of inequality -2
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities：
-2 < a ^ 2 + 2 * a - 3 (1)
a ^ 2 + 2 * a - 3 < -1 (2)
From inequality(1)：
a < -2.414214 或 a ＞ 0.414214
From inequality(2)：
-2.732051 < a < 0.732051
From inequalities (1) and (2)
-2.732051 < a < -2.414214 或 0.414214 < a < 0.732051 (3)
The final solution set is :
-2.732051 < a < -2.414214 或 0.414214 < a < 0.732051 Your problem has not been solved here? Please take a look at the hot problems ！
