76 x^{2} - 72 = 9 - 24 x^{2}

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

Decimal Notation

x = 0.9, x = - 0.9

Solution steps

76 x^{2} - 72 = 9 - 24 x^{2}

Move

72

to the right side

76 x^{2} = - 24 x^{2} + 81

Move

24 x^{2}

to the left 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}

0 = x^{2} - 7

3 x^{2} - 6 x + 1

(4 - y)^{2} + y^{2} = 10

(22 - x)^{2} + (11 - x)^{2} = x^{2}

5 y^{2} - 4 y - 2 = 0
