- 9 x^{2} + 9 = 0

x = 1, x = - 1

Solution steps

- 9 x^{2} + 9 = 0

Move

9

to the right side

- 9 x^{2} = - 9

Divide both sides by

- 9

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

x^{2} + 3 x + 40 = 0

y^{2} = 2 y + 80

x^{2} = 1 - 3 x

30 = x^{2}

3 x^{2} - 3 x = - 7
