81 x^{2} - 121 = 0

x = \frac{11}{9}, x = - \frac{11}{9}

Decimal Notation

x = 1.22222 \dots, x = - 1.22222 \dots

Solution steps

81 x^{2} - 121 = 0

Move

121

to the right side

81 x^{2} = 121

Divide both sides by

81

x^{2} = \frac{121}{81}

For

x^{2} = f (a)

the solutions are

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

x = \frac{121}{81}, x = - \frac{121}{81}

\frac{121}{81} = \frac{11}{9}

- \frac{121}{81} = - \frac{11}{9}

x = \frac{11}{9}, x = - \frac{11}{9}

x^{2} = - 8 + 6 x

\frac{g}{3} - 2 = 1

\frac{y}{6} = \frac{6}{9}

(\frac{- 6 ( r + 4 r ^{2} ) + 9 r ^{2} + 6 r}{3 r})^{2}

5 x = 1
