n^{2} - 4 = 77

n = 9, n = - 9

Solution steps

n^{2} - 4 = 77

Move

4

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

(3 x + 8)^{2} = 12

3 y^{2} = 1 - y

11 y + 2 y^{2} = 21

x, f (a + 1) = 5 x^{2} - x + 4

0 = (x - 5)^{2}
