2 x^{2} - 18 = 46

x = 42, x = - 42

Decimal Notation

x = 5.65685 \dots, x = - 5.65685 \dots

Solution steps

2 x^{2} - 18 = 46

Move

18

to the right side

2 x^{2} = 64

Divide both sides by

2

x^{2} = 32

For

x^{2} = f (a)

the solutions are

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

x = 32, x = - 32

32 = 42

- 32 = - 42

x = 42, x = - 42

2 x^{2} - 16 x + 20 = 0

y, x y^{2} - x^{2} y + 6 = 0

5 x^{2} + 10 x - 15 = 0

7 x^{2} + 1 = 29

x^{2} - 10 x - 4 = 0
