5 x^{2} - 320 = 0

x = 8, x = - 8

Solution steps

5 x^{2} - 320 = 0

Move

320

to the right side

5 x^{2} = 320

Divide both sides by

5

x^{2} = 64

For

x^{2} = f (a)

the solutions are

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

x = 64, x = - 64

64 = 8

- 64 = - 8

x = 8, x = - 8

14 x^{2} + 35 x + 21 = 0

x^{2} + x = 40

46 x^{2} - 75 x + 28125 = 0

(3)^{2} + y^{2} = 49

(2 x + 1) (2 x - 2) = 88
