2 x^{2} - 1400 = 0

x = 107, x = - 107

Solution steps

2 x^{2} - 1400 = 0

Move

1400

to the right side

2 x^{2} = 1400

Divide both sides by

2

x^{2} = 700

For

x^{2} = f (a)

the solutions are

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

x = 700, x = - 700

700 = 107

- 700 = - 107

x = 107, x = - 107

\frac{x ^{2}}{x}

\frac{2}{5} \cdot \frac{2}{10}

h^{2} + 30 h + 200 = 0

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

\frac{a + 13}{10} - \frac{2 a}{5} = \frac{3 - a}{15} + \frac{a}{2}
