(r^{2} + 4) = 0

r = 2 i, r = - 2 i

Solution steps

(r^{2} + 4) = 0

r^{2} + 4 = 0

Move

4

to the right side

r^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

r = - 4, r = - - 4

- 4 = 2 i

- - 4 = - 2 i

r = 2 i, r = - 2 i

9 z^{2} + 14 z = 8 z - 1

\frac{x}{2} + 2 x^{2} = - x (x - 1)

0 = - x^{2} + 4 x

x, x^{2} - y^{2} = c

4 x^{2} + 64 x + 467 = 15
