2 x^{2} = 80

x = 210, x = - 210

Decimal Notation

x = 6.32455 \dots, x = - 6.32455 \dots

Solution steps

2 x^{2} = 80

Divide both sides by

2

x^{2} = 40

For

x^{2} = f (a)

the solutions are

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

x = 40, x = - 40

40 = 210

- 40 = - 210

x = 210, x = - 210

7 x^{2} + 3 x - 4 = 0

15 x^{2} - 135 = 0

12 x^{2} + 2 x - 2 = 0

x^{2} + 13 x - 48 = 0

45 n^{2} + 10 n = 0
