0 = 2 x^{2} - 18

x = 3, x = - 3

Solution steps

0 = 2 x^{2} - 18

Switch sides

2 x^{2} - 18 = 0

Move

18

to the right side

2 x^{2} = 18

Divide both sides by

2

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

3 - x^{2} + 2 x

0 = x (x - 4)

x^{2} = \frac{9}{256}

x^{2} - 21 x - 5 = 0

3 x + 18 = x^{2}
