2 x^{2} - 5 = 13

x = 3, x = - 3

Solution steps

2 x^{2} - 5 = 13

Move

5

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

43 + 23

\frac{b}{8} - \frac{b}{3} \leq - 5

25 x^{2} + 3.92 x - 0.576 = 0

28 + 21 x^{2}

14 (8 - 16 x) \leq - 6
