9 x^{2} - 169 = 0

x = \frac{13}{3}, x = - \frac{13}{3}

Decimal Notation

x = 4.33333 \dots, x = - 4.33333 \dots

Solution steps

9 x^{2} - 169 = 0

Move

169

to the right side

9 x^{2} = 169

Divide both sides by

9

x^{2} = \frac{169}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{169}{9}, x = - \frac{169}{9}

\frac{169}{9} = \frac{13}{3}

- \frac{169}{9} = - \frac{13}{3}

x = \frac{13}{3}, x = - \frac{13}{3}

144 = x^{2} + 10 x

3 x^{2} - 18 x + 15

- 3 (2 x - 1) (2 x + 1) = 2

6 - 7 x^{2} = 7

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