9 x^{2} - 8 = 0

x = \frac{2 2}{3}, x = - \frac{2 2}{3}

Solution steps

9 x^{2} - 8 = 0

Move

8

to the right side

9 x^{2} = 8

Divide both sides by

9

x^{2} = \frac{8}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{8}{9}, x = - \frac{8}{9}

\frac{8}{9} = \frac{2 2}{3}

- \frac{8}{9} = - \frac{2 2}{3}

x = \frac{2 2}{3}, x = - \frac{2 2}{3}

x, x^{2} y^{2} + x y = 1

25 - r^{2} = 4 r

x^{2} + 4 = 2 x^{2} - 12

3 x^{2} - 3 = 45

x^{2} - 2 = 10
