5 x^{2} - 4 = 16

x = 2, x = - 2

Solution steps

5 x^{2} - 4 = 16

Move

4

to the right side

5 x^{2} = 20

Divide both sides by

5

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

8 x^{2} + 22 x + 12 = 0

- 3 x^{2} + 4 x + 59 = - 8 x - 4

(x - 5) (40 - x) = 4 (40 - x)

2 x + x^{2} = 4

x^{2} - 12 x + 36
