x^{2} - 1 = 7 - x^{2}

x = 2, x = - 2

Solution steps

x^{2} - 1 = 7 - x^{2}

Move

1

to the right side

x^{2} = - x^{2} + 8

Move

x^{2}

to the left side

2 x^{2} = 8

Divide both sides by

2

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

- 3 (x + 5)^{2} = 12

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

3 s^{2} + 18 s + 14 = 0

x, z = x^{2} y + 1

A, A BX A - 1 B - 1 = I + A
