You can add simplified square roots only if the radicals are the same and, in that case, you treat the radicals as you would treat a variable in algebra.For example, sqrt(18) + sqrt(50)= sqrt(9*2) + sqrt(25*2)= 3*sqrt(2) + 5*sqrt(2)= [3 + 5]*sqrt(2)= 8*sqrt(2)
There is no number that has more than two square roots.By definition, the "square" bit implies two.Every number has exactly:TWO square roots,THREE cube roots,FOUR quadratic roots,etc.
Yes, a positive square root and a negative one. For example, the two square roots of 9 are +3 and -3.
