100 x^{2} - 81 = 0

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

Decimal Notation

x = 0.9, x = - 0.9

Solution steps

100 x^{2} - 81 = 0

Move

81

to the right side

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}

72 x^{2} - 13 x - 29 = 0

c^{2} = 1^{2} + 3^{2}

x + 6 = - x^{2} - 3 x + 2

x, f = x^{2} + 1

x, f = x^{2} - y
