3 z^{2} - 27 = 0

z = 3, z = - 3

Solution steps

3 z^{2} - 27 = 0

Move

27

to the right side

3 z^{2} = 27

Divide both sides by

3

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

3 x^{2} - 2 (a + b) x - (a + b)^{2} = 0

\frac{( y - 2 ) ^{2}}{3} = 8 - y

4 x^{2} + 4 x - 80 = 0

x, 2 x^{2} - 3 x - 5 = 0

x^{2} + 6 x + 107 = 0
