[math is hard]

3+ 4x-5 (under radical) is less than or equal too 1

dont know how to do radical on computer

If all else fails, you can fake it.

3 + sqrt(4x-5) <= 1

Solve the equality.

3 + sqrt(4x-5) = 1
sqrt(4x-5) = -2 -- Whoops! Stop right there.

We needn't go any farther. You tell me why.

darn, typo it is suppose to be...

3 + sqrt(4x-5) <= 10

OK. Start like I showed you and see where it leads.

Note: If you get an answer less than 5/4, you have to throw it out. Tell me why.

Note: You didn't answer my previous question.
