9 x^{2} + 36 = 0

x = 2 i, x = - 2 i

Solution steps

9 x^{2} + 36 = 0

Move

36

to the right side

9 x^{2} = - 36

Divide both sides by

9

x^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

x = - 4, x = - - 4

- 4 = 2 i

- - 4 = - 2 i

x = 2 i, x = - 2 i

(4 - k) x^{2} + 2 k x + 2 = 0

- 4 x^{2} - 8 x + 32 = 0

- \frac{3}{4} x^{2} + 8 = 0

x, x^{2} + y^{2} + 4 x - 4 y + 8 = 0

23.244 = 0.9 \cdot 210 \cdot x (1 - 0.59 x)
