5 x^{2} = 400

x = 45, x = - 45

Decimal Notation

x = 8.94427 \dots, x = - 8.94427 \dots

Solution steps

5 x^{2} = 400

Divide both sides by

5

x^{2} = 80

For

x^{2} = f (a)

the solutions are

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

x = 80, x = - 80

80 = 45

- 80 = - 45

x = 45, x = - 45

(2 i - 1)^{3}

13 - 14 z = 0

\frac{2 x + 2}{3} = 4

(x^{2} - y^{2}) - [(x + y) (x - y)] + 3 x^{2}

\frac{5}{9} + \frac{4}{18}
