100 x^{2} = 81

x = \frac{9}{10}, x = - \frac{9}{10}

Decimal Notation

x = 0.9, x = - 0.9

Solution steps

100 x^{2} = 81

Divide both sides by

100

x^{2} = \frac{81}{100}

For

x^{2} = f (a)

the solutions are

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

x = \frac{81}{100}, x = - \frac{81}{100}

\frac{81}{100} = \frac{9}{10}

- \frac{81}{100} = - \frac{9}{10}

x = \frac{9}{10}, x = - \frac{9}{10}

100 x^{2} = 49

x^{2} + 8 x + 12

x^{2} + 8 x + 20

- x^{2} - 3 x + 87 = 4 x + 27

2 x^{2} = - 18 x - 36
