I think you had your parenthesis in the wrong place. Problem is likely:
sqrt%287x%2B2%29%3C4
Let me know if this is incorrect.
=======================
First, square both sides of the inequality. This gets rid of the radical:
7x%2B2%3C16
Solve for x:
7x%3C14
highlight%28x%3C2%29
===============
Good Luck,
