- 2 x^{2} = - 168

x = 221, x = - 221

Decimal Notation

x = 9.16515 \dots, x = - 9.16515 \dots

Solution steps

- 2 x^{2} = - 168

Divide both sides by

- 2

x^{2} = 84

For

x^{2} = f (a)

the solutions are

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

x = 84, x = - 84

84 = 221

- 84 = - 221

x = 221, x = - 221

x^{2} + 2 x y - 15 y^{2}

2 x^{2} + 3 x - 5

8 x^{2} - 2 x - 1 = 0

x^{\frac{1}{2}} \cdot 3 x^{2}

4 x^{4} + 5 x^{2} + 1
