81 x^{2} = 169

x = \frac{13}{9}, x = - \frac{13}{9}

Decimal Notation

x = 1.44444 \dots, x = - 1.44444 \dots

Solution steps

81 x^{2} = 169

Divide both sides by

81

x^{2} = \frac{169}{81}

For

x^{2} = f (a)

the solutions are

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

x = \frac{169}{81}, x = - \frac{169}{81}

\frac{169}{81} = \frac{13}{9}

- \frac{169}{81} = - \frac{13}{9}

x = \frac{13}{9}, x = - \frac{13}{9}

r^{2} - 3 r = 0

9 a^{2} = 81

- x^{2} - 2 x + 4 = 2 - 2 x

2 x^{2} - 4 x + 8 = 5 x^{2} + 2 x - 5

2 (x + 1)^{2} - 3 = 95
