x^{2} - 7 = - 88

x = 9 i, x = - 9 i

Solution steps

x^{2} - 7 = - 88

Move

7

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 i

- - 81 = - 9 i

x = 9 i, x = - 9 i

18 - 4 x - 5 x^{2} = 3

18 x^{2} - 6 x = 0

(2 x - 13)^{2} = 24

4 x^{2} - 7 x = - 5

x, 2 x^{2} + 2 y^{2} - 2 x - 2 y + 9 = 0
