The equation x^{2} - 144 = 0 has a positive integer solution of x = 12. Find its other solution.
Solve the following equations:
x^{2} = 2
x^{2} = 25
x^{2} = 121
x^{2} = 294
x^{2} - 121 = 0
x^{2} - 10 = 15
\dfrac{x^{2}}{16} - 2 = 2
\dfrac{x^{2}}{25} - 3 = 6
\left(x + 3\right)^{2} = 49
\left(x - 3\right)^{2} = 64
\left(x - 6\right)^{2} = 2
\left(2 - x\right)^{2} = 81
\left(x - 7\right)^{2} = 81
\left(7 - x\right)^{2} = 81
\left( 8 x + 9\right)^{2} = 256
81 x^{2} - 16 = 0
Solve the following equations:
4 y^{2} = 100
25 y^{2} = 36
- 3 k^{2} = - 12
81 k^{2} + 8 = 24
- 25 v^{2} + 64 = 0
10 \left(p^{2} - 7\right) = 930
