z^{2} + 49 = 0

z = 7 i, z = - 7 i

Solution steps

z^{2} + 49 = 0

Move

49

to the right side

z^{2} = - 49

For

x^{2} = f (a)

the solutions are

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

z = - 49, z = - - 49

- 49 = 7 i

- - 49 = - 7 i

z = 7 i, z = - 7 i

x^{2} + 5 x = 23 - x

- 3 x^{2} - 6 x - 4 = 0

y, x^{2} y + x y^{2} = 3 x

5 x^{2} + 13 x - 18 = 0

12 x^{2} + 24 x - 15 = 0
