One solution of x²-49=0 is -7. To find the other solution, we first need to solve the equation x²-49=0.
1. Add 49 to both sides of the equation to isolate x²: x² = 49.
2. Take the square root of both sides to solve for x: x = ±√49.
3. √49 = 7, so x can be either 7 or -7.
Therefore, the other solution for the equation x²-49=0 is 7. The solutions are x = -7 and x = 7.
