9 x^{2} - 18 = 7

x = \frac{5}{3}, x = - \frac{5}{3}

Decimal Notation

x = 1.66666 \dots, x = - 1.66666 \dots

Solution steps

9 x^{2} - 18 = 7

Move

18

to the right side

9 x^{2} = 25

Divide both sides by

9

x^{2} = \frac{25}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{25}{9}, x = - \frac{25}{9}

\frac{25}{9} = \frac{5}{3}

- \frac{25}{9} = - \frac{5}{3}

x = \frac{5}{3}, x = - \frac{5}{3}

3 e (3 + \frac{iπ}{6})

- \frac{7}{4} = \frac{2}{5} t

(8 + 2 x) (26 + 2 x) = 448

\frac{4}{5 - 3}

\frac{5 x + 1}{2} = 4 x - 7
