u^{2} = - 81

u = 9 i, u = - 9 i

Solution steps

u^{2} = - 81

For

x^{2} = f (a)

the solutions are

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

u = - 81, u = - - 81

- 81 = 9 i

- - 81 = - 9 i

u = 9 i, u = - 9 i

x^{2} - 6 x - 14 = 0

\frac{13 !}{( 13 - 4 ) 3 !}

4 ∣ 6 + 2 s ∣ - 27 \leq - 3

\frac{1}{x} < 4

8 (- 2 x - 4) + 12 = - 52
