r^{2} + 9 = 0

r = 3 i, r = - 3 i

Solution steps

r^{2} + 9 = 0

Move

9

to the right side

r^{2} = - 9

For

x^{2} = f (a)

the solutions are

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

r = - 9, r = - - 9

- 9 = 3 i

- - 9 = - 3 i

r = 3 i, r = - 3 i

\frac{x - 3}{3 x + 7} \leq 3

- x^{2} - 3 x + 28

3 (x + 8)^{2} - 20 = 28

(64 x)^{\frac{1}{6}}

y - 3 > 10
