- 2 x^{2} + 4 = 0

x = 2, x = - 2

Decimal Notation

x = 1.41421 \dots, x = - 1.41421 \dots

Solution steps

- 2 x^{2} + 4 = 0

Move

4

to the right side

- 2 x^{2} = - 4

Divide both sides by

- 2

x^{2} = 2

For

x^{2} = f (a)

the solutions are

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

x = 2, x = - 2

\frac{4}{3} \cdot \frac{4}{3} \cdot \frac{4}{3}

2 m^{2} - 50

90 = s + \frac{s ^{2}}{10}

- x + 4 < \frac{1}{2} x + 1
