2 x^{2} - 80 = 0

x = 210, x = - 210

Decimal Notation

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

Solution steps

2 x^{2} - 80 = 0

Move

80

to the right side

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

(x - 3) (x - 4)^{2} < 0

3^{3} \cdot 3^{- 5}

3 x^{2} - 9 x - 8 = 0

9 \cdot 25
