Hello Jimmi2401. So this is the problem:
right? You really need to learn how to use parentheses and/or brackets to group terms. You should have written this as:
s = sqrt[(t-q)/(t+2q)]
OK - now that we have the problem properly defined - next step is for you to show us what you've tried so far to solve this, and where you are getting stuck. Then we'll be glad to help you out. But here's a hint: start by squaring both sides.
