- 4 x^{2} - 16 = 0

x = 2 i, x = - 2 i

Solution steps

- 4 x^{2} - 16 = 0

Move

16

to the right side

- 4 x^{2} = 16

Divide both sides by

- 4

x^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

x = - 4, x = - - 4

- 4 = 2 i

- - 4 = - 2 i

x = 2 i, x = - 2 i

10 x^{2} + 15 x + 4 = 0

x, y = (x + 4)^{2}

9 w^{2} + 30 w = - 25

- 4.9 x^{2} + 4.3301200000000 \dots x - 0.8 = 0

x^{2} + 2 x - 21 = 0
