Do I square it so that it becomes the following?

Thanks. - Oct 10th 2010, 11:48 PMmr fantastic
The first thing you need to understand is that so even if the correct approach was to square both sides of the given equation, the result you got is very wrong.

can be solved using the usual quadratic formula in the usual way. If you need more help, please show your work and say where you get stuck. - Oct 11th 2010, 02:02 AMKyrie
Thank you for the reply. I guess the radicals scared me. :P

I get stuck when I rationalize the denominator.

Step 1 = Use Quadratic formula

Step 2 = Evaluate

Step 3 = Rationalize denominator

But the answer says the denominator should be 4. What am I doing wrong? - Oct 11th 2010, 02:41 AMharish21
