x^{2} - 8 = 12

x = 25, x = - 25

Decimal Notation

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

Solution steps

x^{2} - 8 = 12

Move

8

to the right side

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

4 - 2 x + x^{2} = 0

2 a^{2} - 3 a + \frac{1}{4} = 0

45 - 19 x + 2 x^{2} = 0

x^{2} + a^{2} - 2 x - 6 a = 6 x - 2 a

2 x^{2} + 4 x = - 3 x^{2} + x - 5
