- x^{2} - 20 = 0

x = 25 i, x = - 25 i

Solution steps

- x^{2} - 20 = 0

Move

20

to the right side

- x^{2} = 20

Divide both sides by

- 1

x^{2} = - 20

For

x^{2} = f (a)

the solutions are

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

x = - 20, x = - - 20

- 20 = 25 i

- - 20 = - 25 i

x = 25 i, x = - 25 i

4 x^{2} = - 144

12 x^{2} - 10 x + 2 = 0

t^{2} - 4 t + 3 = 0

0 = z^{2} - 10 z + 25

2 x^{2} - 3 x + 1
