You can put this solution on YOUR website!
If 5x + x² > 100, then x is not
--------------------------------------------

x%5E2%2B5x-100%3E0
Discriminant, 125

Roots, %28-5%2B-+5sqrt%285%29%29%2F2
x is not between these roots.




These you can simply solve
----------------------------
If 2(x -1) = 14, then x =


If 5x - 17 = -x + 7, then x =
----------------------------
