x^{2} - 77 = 4

x = 9, x = - 9

Solution steps

x^{2} - 77 = 4

Move

77

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

4 x^{2} + 8 x + 3

2 x^{2} - 8 x + 16 = 0

x, x^{2} + y^{2} = x y

3 x^{2} - 5 x = 7

10 + 5 x^{2} = 55
