Applicable to this and all other questions-- For any solution that involves two answers, type one answer separated by a comma and then the other answer. Solve the equation x2 = 81 by finding square roots.

    x^2 = 81 you actually mean this sqrt(x^2)=sqrt(81) take sqrt of both sides x= 9 or x=-9 both work but since it says seperate answer by commas it is 9,-9
