9 x^{2} - 7 = 0

x = \frac{7}{3}, x = - \frac{7}{3}

Solution steps

9 x^{2} - 7 = 0

Move

7

to the right side

9 x^{2} = 7

Divide both sides by

9

x^{2} = \frac{7}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{7}{9}, x = - \frac{7}{9}

\frac{7}{9} = \frac{7}{3}

- \frac{7}{9} = - \frac{7}{3}

x = \frac{7}{3}, x = - \frac{7}{3}

36 x^{2} - 49 y^{2}

1 (\frac{3}{7})^{2}

49 - 16 x^{2} y^{2}

7 f (g + h) + (g + h)^{2}

2 y^{2} - 10 y - 2 = - 12 y
