x^{2} + 4 = 20

x = 4, x = - 4

Solution steps

x^{2} + 4 = 20

Move

4

to the right side

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

2 x^{2} - 3 x - 5 = - 10 x

x^{2} - 2 x + 17

e^{2} = 0

- 6 x^{2} + 12 x + 210 = 0

x^{2} - 2 x = 12 - x^{2}
