2 x^{2} - 5 = - 205

x = 10 i, x = - 10 i

Solution steps

2 x^{2} - 5 = - 205

Move

5

to the right side

2 x^{2} = - 200

Divide both sides by

2

x^{2} = - 100

For

x^{2} = f (a)

the solutions are

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

x = - 100, x = - - 100

- 100 = 10 i

- - 100 = - 10 i

x = 10 i, x = - 10 i

x^{2} - 12 = 4 x

x^{2} - 15 x - 100 = 0

- 80 + y = 80

3 ∣ y ∣ = 0

- 7 x^{2} + 2 x - 1 = 0
