x^{2} + 3 = 2 x^{2} - 1

x = 2, x = - 2

Solution steps

x^{2} + 3 = 2 x^{2} - 1

Move

3

to the right side

x^{2} = 2 x^{2} - 4

Move

2 x^{2}

to the left side

- x^{2} = - 4

Divide both sides by

- 1

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

(x - 6)^{2} - 1 = 0

2 x (x - 2) = 9

x^{2} - 6 x - 8 = 0

x^{2} + 2 x - 99 = 0

4 v^{2} + 4 = 40
