a^{2} = 20

a = 25, a = - 25

Decimal Notation

a = 4.47213 \dots, a = - 4.47213 \dots

Solution steps

a^{2} = 20

For

x^{2} = f (a)

the solutions are

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

a = 20, a = - 20

20 = 25

- 20 = - 25

a = 25, a = - 25

a^{2} = 11

\frac{2}{3} x^{2} + \frac{4}{3} x = 0

- 16 t^{2} + 40 = 0

(t + 4)^{2} - 12 (t + 4) + 35 = 0

9 p^{2} - 24 p + 11 = 0
