(z - 2)^{2} - 30 = 6

z = 8, z = - 4

Solution steps

(z - 2)^{2} - 30 = 6

Move

30

to the right side

(z - 2)^{2} = 36

For

(g (x))^{2} = f (a)

the solutions are

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

Solve

z - 2 = 36 : z = 8

Solve

z - 2 = - 36 : z = - 4

The solutions to the quadratic equation are:

z = 8, z = - 4

3 p^{2} - p + 5 = 0

x^{2} + 1 = 9

0 = x^{2} + 6 x + 7

z^{2}

- 5 x^{2} + 125 x = 0
