x^{2} + 2 x + 5 = 0

x = 2 i - 1, x = - 2 i - 1

Solution steps

x^{2} + 2 x + 5 = 0

Move

5

to the right side

x^{2} + 2 x = - 5

Rewrite in the form

(x + a)^{2} = b

(x + 1)^{2} = - 4

For

the solutions are

f (x) = a, - a

Solve

x + 1 = - 4 : x = 2 i - 1

Solve

x + 1 = - - 4 : x = - 2 i - 1

The solutions to the quadratic equation are:

x = 2 i - 1, x = - 2 i - 1

(x + 3) (2 x - 7) = 0

c^{2} + 6 c + 5 = 0

5 x^{2} + 10 x + 20 = 0

t^{2} - 14 t = - 50

16 x^{2} - 40 x + 221 = 0
