3 x^{2} - 243 = 0

x = 9, x = - 9

Solution steps

3 x^{2} - 243 = 0

Move

243

to the right side

3 x^{2} = 243

Divide both sides by

3

x^{2} = 81

For

x^{2} = f (a)

the solutions are

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

x = 81, x = - 81

81 = 9

- 81 = - 9

x = 9, x = - 9

(x + 2)^{3} (x - 1) \geq 0

u^{2} = 16
