I could have sworn back in algebra 2 we were supposed to put the +/- answers on things that used the square root symbol (assuming we're talking about the thing that looks like the V in the Vans shoe logo) you use the +/- if you have an equation like x^2 = 9. Thus x = +/- 3. That is different from x = sqrt(9), which only has the answer 3. <cite>Fam_Fam posted [p:887436868] in why doesn'...

Fam_Fam 09/28/17 7:04:56 AM #9:	If we mean the radical symbol when we say sqrt, then sqrt(9) = 3, not -3, not +/3.
