- 9 - 8 x^{2} = - 209

x = 5, x = - 5

Solution steps

- 9 - 8 x^{2} = - 209

Move

9

to the right side

- 8 x^{2} = - 200

Divide both sides by

- 8

x^{2} = 25

For

x^{2} = f (a)

the solutions are

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

x = 25, x = - 25

25 = 5

- 25 = - 5

x = 5, x = - 5

x^{2} + 2 x - 143 = 0

m^{2} + 2 m - 48 = - 6

x^{2} + 2 x = 319

y^{2} - 12 y + 36 = 49

2 a^{2} - a - 1 = 0
