8 x^{2} - 5 = 11

x = 2, x = - 2

Decimal Notation

x = 1.41421 \dots, x = - 1.41421 \dots

Solution steps

8 x^{2} - 5 = 11

Move

5

to the right side

8 x^{2} = 16

Divide both sides by

8

x^{2} = 2

For

x^{2} = f (a)

the solutions are

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

x = 2, x = - 2

z^{2} = 3

x^{2} = \frac{x ^{2}}{2} + 2

x = x^{2} - 12 x + 36

x^{2} - 10 x + 15 = - 7

3 x^{2} - \frac{1}{3} = 0
