2 - 4 x^{2} = - 110

x = 27, x = - 27

Decimal Notation

x = 5.29150 \dots, x = - 5.29150 \dots

Solution steps

2 - 4 x^{2} = - 110

Move

2

to the right side

- 4 x^{2} = - 112

Divide both sides by

- 4

x^{2} = 28

For

x^{2} = f (a)

the solutions are

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

x = 28, x = - 28

28 = 27

- 28 = - 27

x = 27, x = - 27

1 - (2 π)^{2} = - a^{2}

2 x^{2} - 10 x - 20 = 0

x, y^{2} - 2 y - 4 x^{2} - 16 x = 15

x, z = 2 x^{2} - 3 x y + 4 y^{2}

- 4 x^{2} - 8 x + 5 = 0
