a^{2} + 4 = 0

a = 2 i, a = - 2 i

Solution steps

a^{2} + 4 = 0

Move

4

to the right side

a^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

a = - 4, a = - - 4

- 4 = 2 i

- - 4 = - 2 i

a = 2 i, a = - 2 i

8 x^{2} + 12 x + 7 = 0

x, x^{2} + y^{2} = 11 x y

x^{2} + 13 x - 68 = 0

\frac{1}{10} y^{2} = - y - \frac{5}{2}

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