64 x^{2} - 81 = 0

x = \frac{9}{8}, x = - \frac{9}{8}

Decimal Notation

x = 1.125, x = - 1.125

Solution steps

64 x^{2} - 81 = 0

Move

81

to the right side

64 x^{2} = 81

Divide both sides by

64

x^{2} = \frac{81}{64}

For

x^{2} = f (a)

the solutions are

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

x = \frac{81}{64}, x = - \frac{81}{64}

\frac{81}{64} = \frac{9}{8}

- \frac{81}{64} = - \frac{9}{8}

x = \frac{9}{8}, x = - \frac{9}{8}

(x - 5)^{2} = 4
