- x^{2} - 3.5 = - 12.5

x = 3, x = - 3

Solution steps

- x^{2} - 3.5 = - 12.5

Move

3.5

to the right side

- x^{2} = - 9

Divide both sides by

- 1

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

11 x^{2} - 22 x = - 11

- 16 t^{2} + 256 = 0

3 x^{2} - 5 = - 5 x - 3

16 x^{2} + 11 = - 24 x

0 = x^{2} + 6 x + 9
