x^{2} + 9 = - 40

x = 7 i, x = - 7 i

Solution steps

x^{2} + 9 = - 40

Move

9

to the right side

x^{2} = - 49

For

x^{2} = f (a)

the solutions are

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

x = - 49, x = - - 49

- 49 = 7 i

- - 49 = - 7 i

x = 7 i, x = - 7 i

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

5 t^{2} + 10 t - 40 = 0

- 33 x^{2} + 14 x + 5 = 0

16 x^{2} - 8 x + 1 = 0

k (k - 3) = 0
