y^{2} - 9 = 0

y = 3, y = - 3

Solution steps

y^{2} - 9 = 0

Move

9

to the right side

y^{2} = 9

For

x^{2} = f (a)

the solutions are

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

y = 9, y = - 9

9 = 3

- 9 = - 3

y = 3, y = - 3

- 2 x < 2

\frac{4 ^{2}}{- 3}

\frac{x}{5} - 2 + \frac{x}{5} = \frac{14}{5}

x^{2} + 1 x - 1

3 - 2 x > 0
