20 = x^{2}

x = 25, x = - 25

Decimal Notation

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

Solution steps

20 = x^{2}

Switch sides

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

6 a^{2} - 2 a = 7

25 = 4 x^{2} - 5 x - 50

1 = \frac{1}{3} (4 v + 3)

6 - \frac{1}{6} x = \frac{16}{3}

5 x - \frac{2}{5} \leq 2 - \frac{7 x}{2} < 3
