12 - 2 x^{2} = - 20

x = 4, x = - 4

Solution steps

12 - 2 x^{2} = - 20

Move

12

to the right side

- 2 x^{2} = - 32

Divide both sides by

- 2

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

y, x^{2} + x y - y^{2} = 4

y, x^{2} y^{2} - 4 x^{2} - 4 y^{2} = 0

x^{2} - 6 x + 10

x^{2} - 36 = 0

19 + 2 x^{2} = 21
