$\pm 15$

what does this mean real square roots? square roots are positive. that is what it means "square root" of something. it is not the same as saying solve for x $x^2=225$ where the answer is $\pm 15$

if they are teaching you that there are two square roots of 225 they are mistaken. there are two solutions to $x^2=225$ but there is only one $\sqrt{225}$

^ Depends on who you ask :D When they say "real," I go for ALL real answers :D
