5 x^{2} - 120 = 5

x = 5, x = - 5

Solution steps

5 x^{2} - 120 = 5

Move

120

to the right side

5 x^{2} = 125

Divide both sides by

5

x^{2} = 25

For

x^{2} = f (a)

the solutions are

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

x = 25, x = - 25

25 = 5

- 25 = - 5

x = 5, x = - 5

\frac{1}{20} x^{2} + 4 x + 100 = 0

x^{2} + 20 x - 8 = 0

- 2 x^{2} + 8 x + 10 = 0

2 x^{2} = - x - 10

6 x^{2} + 9 = - 55 x
