x^{2} - 2 = - 1

x = 1, x = - 1

Solution steps

x^{2} - 2 = - 1

Move

2

to the right side

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 = 2 x

3 x^{2} + 12 x - 135 = 0

2^{2} + b^{2} = 9^{2}

y^{2} - 4 y - 3 = 0

3 a^{2} - 5 = 70
