z^{2} - 9 = 0

z = 3, z = - 3

Solution steps

z^{2} - 9 = 0

Move

9

to the right side

z^{2} = 9

For

x^{2} = f (a)

the solutions are

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

z = 9, z = - 9

9 = 3

- 9 = - 3

z = 3, z = - 3

5^{2} + 9^{2} = x^{2}

x, x^{2} + 4 x + 1 = 0

x^{2} - 8 x - 18 = 0

3 x^{2} - 12 = - 16 x

y^{2} - 8 y = 9
