2 x^{2} - 9 = 55

x = 42, x = - 42

Solution steps

2 x^{2} - 9 = 55

Move

9

to the right side

2 x^{2} = 64

Divide both sides by

2

x^{2} = 32

For

x^{2} = f (a)

the solutions are

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

x = 32, x = - 32

32 = 42

- 32 = - 42

x = 42, x = - 42

1 + \frac{2 b}{3} + \frac{b ^{2}}{9} = 0

2 x^{2} + 16 x + 34 = 0

- 12 x^{2} - 54 x = 0

- 3 x^{2} + 48 = 0

3 x^{2} + 6 x - 2 = - 2
