4 x^{2} - 20 = 0

x = 5, x = - 5

Solution steps

4 x^{2} - 20 = 0

Move

20

to the right side

4 x^{2} = 20

Divide both sides by

4

x^{2} = 5

For

x^{2} = f (a)

the solutions are

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

x = 5, x = - 5

12 x^{2} - 10 x - 8

3 x - 15 = 12

2 x - x^{2} = 2

0.25 t = 0.25 - t

x^{2} = 48
