- 9 x^{2} = - 1

x = \frac{1}{3}, x = - \frac{1}{3}

Decimal Notation

x = 0.33333 \dots, x = - 0.33333 \dots

Solution steps

- 9 x^{2} = - 1

Divide both sides by

- 9

x^{2} = \frac{1}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{1}{9}, x = - \frac{1}{9}

\frac{1}{9} = \frac{1}{3}

- \frac{1}{9} = - \frac{1}{3}

x = \frac{1}{3}, x = - \frac{1}{3}

7 x^{2} = 2 x - 1

x (x + 5) = 3 x^{2} - 4

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

x^{2} - 15 x + 16 = 0

x, x^{2} + x y = 1
