x^{2} - 4 = 77

x = 9, x = - 9

Solution steps

x^{2} - 4 = 77

Move

4

to the right side

x^{2} = 81

For

x^{2} = f (a)

the solutions are

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

x = 81, x = - 81

81 = 9

- 81 = - 9

x = 9, x = - 9

(2 x + 1) (x - 4) = 3

3 a^{2} + 22 a - 45

\frac{3 x - 1}{∣ x - 1 ∣} \geq 4

14 x = 10

x^{6} + c^{2} x^{4} + c^{4} x^{2} + c^{6}
