2 x^{2} - 17 = 81

x = 7, x = - 7

Solution steps

2 x^{2} - 17 = 81

Move

17

to the right side

2 x^{2} = 98

Divide both sides by

2

x^{2} = 49

For

x^{2} = f (a)

the solutions are

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

x = 49, x = - 49

49 = 7

- 49 = - 7

x = 7, x = - 7

\frac{- 1}{x} < 2

2 \cdot 2^{\frac{1}{2}}

22

\frac{x}{1} + 5 > 5

(2 - i)^{2}
