8 x^{2} - 20 = 0

x = \frac{5}{2}, x = - \frac{5}{2}

Decimal Notation

x = 1.58113 \dots, x = - 1.58113 \dots

Solution steps

8 x^{2} - 20 = 0

Move

20

to the right side

8 x^{2} = 20

Divide both sides by

8

x^{2} = \frac{5}{2}

For

x^{2} = f (a)

the solutions are

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

x = \frac{5}{2}, x = - \frac{5}{2}

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

- 2 x^{2} = - 72

x^{2} - 4 x - 7

8 - x^{2} = 2 x

y - y^{2} = y^{2} - 3
