225 x^{2} = 9

x = \frac{1}{5}, x = - \frac{1}{5}

Decimal Notation

x = 0.2, x = - 0.2

Solution steps

225 x^{2} = 9

Divide both sides by

225

x^{2} = \frac{1}{25}

For

x^{2} = f (a)

the solutions are

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

x = \frac{1}{25}, x = - \frac{1}{25}

\frac{1}{25} = \frac{1}{5}

- \frac{1}{25} = - \frac{1}{5}

x = \frac{1}{5}, x = - \frac{1}{5}

4 w^{2} + w - 2 = 0

4 x^{2} - 14 x - 98 = 0

- 2 x^{2} + 3 x + 15 = 4 x

x^{2} + 4 x + 100 = 0

x^{2} - 3 = 78
