- 2 z^{2} = - 72

z = 6, z = - 6

Solution steps

- 2 z^{2} = - 72

Divide both sides by

- 2

z^{2} = 36

For

x^{2} = f (a)

the solutions are

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

z = 36, z = - 36

36 = 6

- 36 = - 6

z = 6, z = - 6

3 x^{2} + 6 x - a = 0

x^{2} - 2 x - x = 1

50 x^{2} + 5 (x - 2)^{2} = - 1

3 (x^{2} - 5) = - (9 x + 1) - (x + 2) (x - 3)

5 m^{2} - 9 m = - 4
