☆6 inequalities
[ 1/6Inequality]
Assignment:Find the solution set of inequality x^2-x-2 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
x ^ 2 - x - 2 >0 (1)
From inequality(1)：
x < -1 或 x ＞ 2
The final solution set is :
x < -1 或 x ＞ 2[ 2/6Inequality]
Assignment:Find the solution set of inequality x^2-2x-2 <0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
x ^ 2 - 2 * x - 2 <0 (1)
From inequality(1)：
-0.732051 < x < 2.732051
The final solution set is :
-0.732051 < x < 2.732051 [ 3/6Inequality]
Assignment:Find the solution set of inequality x^2-3x >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
x ^ 2 - 3 * x >0 (1)
From inequality(1)：
x < 0 或 x ＞ 3
The final solution set is :
x < 0 或 x ＞ 3[ 4/6Inequality]
Assignment:Find the solution set of inequality x <15 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
x <15 (1)
From inequality(1)：
x < 15
The final solution set is :
x < 15[ 5/6Inequality]
Assignment:Find the solution set of inequality x >-13 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
x > -13 (1)
From inequality(1)：
x ＞ -13
The final solution set is :
x ＞ -13[ 6/6Inequality]
Assignment:Find the solution set of inequality (x+13)^2-28(x^2-x-2) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
( x + 13 ) ^ 2 - 28 * ( x ^ 2 - x - 2 ) >0 (1)
From inequality(1)：
-2.05505 < x < 4.05505
The final solution set is :
-2.05505 < x < 4.05505 Your problem has not been solved here? Please take a look at the hot problems ！
