u^{2} = 20

u = 25, u = - 25

Decimal Notation

u = 4.47213 \dots, u = - 4.47213 \dots

Solution steps

u^{2} = 20

For

x^{2} = f (a)

the solutions are

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

u = 20, u = - 20

20 = 25

- 20 = - 25

u = 25, u = - 25

- 0.5 x^{2} + 36 x - 522 = 0

2 x^{2} + 40 x = - 72

0 = - 810 a + a^{2} + 256064.9

x^{2} + 12 x + 3 = 0

9 x^{2} = 3 x
