x^{2} = 84

x = 221, x = - 221

Decimal Notation

x = 9.16515 \dots, x = - 9.16515 \dots

Solution steps

x^{2} = 84

For

x^{2} = f (a)

the solutions are

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

x = 84, x = - 84

84 = 221

- 84 = - 221

x = 221, x = - 221

6 ∣ u ∣ = 0

- x^{2} - x + 20

6 x + 9 = 63

45 x + 30

x < 4 or x < 5
