5 x^{2} - 60 = 20

x = 4, x = - 4

Solution steps

5 x^{2} - 60 = 20

Move

60

to the right side

5 x^{2} = 80

Divide both sides by

5

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

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

(x - 1)^{2} + 11 x - 199 = 3 x^{2} - (x - 2)^{2}

12.835 = y ((11.1294 - 3.65 y) + 1.5 y)

16 x^{2} - 18 = 7

5 a^{2} - a - 6 = 0
