u^{2} + 4 = 0

u = 2 i, u = - 2 i

Solution steps

u^{2} + 4 = 0

Move

4

to the right side

u^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

u = - 4, u = - - 4

- 4 = 2 i

- - 4 = - 2 i

u = 2 i, u = - 2 i

x, 3 x^{2} - 2 y^{3} D x y = 0

x^{2} - 10 x + 25 = 25

- 2 x^{2} - 6 x - 3 = 0

x^{2} + 13 + 42 = 0

6 x^{2} + 13 x - 63 = 0
