3 y^{2} - 27 = 0

y = 3, y = - 3

Solution steps

3 y^{2} - 27 = 0

Move

27

to the right side

3 y^{2} = 27

Divide both sides by

3

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

- 4 x^{2} - 7 x + 12 = 0

s^{2} - 4 s + 8 = 0

x^{2} + 10 x = 56

x^{2} - 18 x + 9 = 0

x^{2} + 49 - 14 x + x^{2} = 25
