8 x^{2} - 5 = 251

x = 42, x = - 42

Decimal Notation

x = 5.65685 \dots, x = - 5.65685 \dots

Solution steps

8 x^{2} - 5 = 251

Move

5

to the right side

8 x^{2} = 256

Divide both sides by

8

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

(x - 9) (x + 2) = 0

(- 2 x + 5)^{2} = - 8

12 x^{2} - 488 x + 3321 = 0

x, 4 z^{2} - x^{2} - y + 16 z + 4 z + 20 = 0

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