2 x^{2} = 40

x = 25, x = - 25

Decimal Notation

x = 4.47213 \dots, x = - 4.47213 \dots

Solution steps

2 x^{2} = 40

Divide both sides by

2

x^{2} = 20

For

x^{2} = f (a)

the solutions are

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

x = 20, x = - 20

20 = 25

- 20 = - 25

x = 25, x = - 25

100 (1) + 100 (9) + (m - 999.5) (22) = 2500
