2 x^{2} = 120

x = 215, x = - 215

Decimal Notation

x = 7.74596 \dots, x = - 7.74596 \dots

Solution steps

2 x^{2} = 120

Divide both sides by

2

x^{2} = 60

For

x^{2} = f (a)

the solutions are

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

x = 60, x = - 60

60 = 215

- 60 = - 215

x = 215, x = - 215

2 x^{2} = 11 x

5 r^{2} - 8 r = 0

4 x^{2} + 8 x = 9

x^{2} + 2 = 8

x^{2} - (- 3 + (- 6)) x + (- 3 \cdot (- 6)) = 0
