Solve for the variable: (square root of)(2x + 1) = -1
a) 0
b) 1
c) -1
d) -2
none of these
You can't take the square root of anything and get a negative number, so you can look at this and know that this has no solution, however, if you didn't notice that, you would try to solve it this way.

But when you check x=0, you will find that it's extraneous.

Not true, so 0 is extraneous and there is no solution.
Happy Calculating!!!
