n^{2} - 81 = 0

n = 9, n = - 9

Solution steps

n^{2} - 81 = 0

Move

81

to the right side

n^{2} = 81

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

n = 81, n = - 81

81 = 9

- 81 = - 9

n = 9, n = - 9

- 7 - c^{2} = - 17

4 r^{2} + 18 r + 13 = - 2

- 2 x^{2} - 40 x - 224 = 0

(3 x + 2) (x - 1) = 3 x

6 x^{2} + x + 1 = 0
