Question

1 Answer/Comment
x^2 = 81
when x*x = 9*9 , x= 9
when x*x= (-9)*(-9) , x= -9
So the solution for x^2 = 81 is {-9 ,9} .

1 Answer/Comment
x^2 = 81
x^2 - 81= 0
(x - 9)(x+ 9) = 0
when x - 9 = 0 , x = 9
when x + 9 = 0 , x = -9

Question
Updated 12/4/2014 2:17:39 AM
1 Answer/Comment
x^2 - 2x + 1 = 18
(x - 1)^2 = 18
x - 1 = ±3*2^1/2
x = ±3*2^1/2 + 1

1 Answer/Comment
x^2 - 2x - 8 = 0;
(x - 4)(x + 2) = 0;
x - 4 = 0;
x = 4;
x + 2 = 0;
x = -2;
The sum of of the solutions of x^2 - 2x -8 = 0 is 2.
4 + (-2) = 2
