2 x^{2} - 30 = 2

x = 4, x = - 4

Solution steps

2 x^{2} - 30 = 2

Move

30

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

x (x - 8) = 9

x, - x^{2} + \frac{36 y ^{2}}{25} = 0

x^{2} - 4 x + 4 = 0

t^{2} = 81

t (13 - t) = 40
