- 4.91 x^{2} + 2 = 0

x = \frac{10 2}{491}, x = - \frac{10 2}{491}

Decimal Notation

x = 0.63822 \dots, x = - 0.63822 \dots

Solution steps

- 4.91 x^{2} + 2 = 0

Move

2

to the right side

- 4.91 x^{2} = - 2

Multiply both sides by

100

- 491 x^{2} = - 200

Divide both sides by

- 491

x^{2} = \frac{200}{491}

For

x^{2} = f (a)

the solutions are

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

x = \frac{200}{491}, x = - \frac{200}{491}

\frac{200}{491} = \frac{10 2}{491}

- \frac{200}{491} = - \frac{10 2}{491}

x = \frac{10 2}{491}, x = - \frac{10 2}{491}

x^{2} + (x + 1)^{2} + (x + 2)^{2} = 110

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

70840 - 188 d - 2.35 d^{2} = 1228.8 d + 30.72 d^{2}
