2 x^{2} - 1 \frac{7}{25} = 0

x = \frac{4}{5}, x = - \frac{4}{5}

Decimal Notation

x = 0.8, x = - 0.8

Solution steps

2 x^{2} - 1 \frac{7}{25} = 0

Convert mixed numbers to improper fractions:

1 \frac{7}{25} = \frac{32}{25}

2 x^{2} - \frac{32}{25} = 0

Move

\frac{32}{25}

to the right side

2 x^{2} = \frac{32}{25}

Divide both sides by

2

x^{2} = \frac{16}{25}

For

x^{2} = f (a)

the solutions are

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

x = \frac{16}{25}, x = - \frac{16}{25}

\frac{16}{25} = \frac{4}{5}

- \frac{16}{25} = - \frac{4}{5}

x = \frac{4}{5}, x = - \frac{4}{5}

a x^{2} + 2 x + 1 = 0

2 x^{2} + 3 x - 1

25 x^{2} - 10 x = - 1

x, y = 2 x^{2} - 12 x - 11

96 x^{2} + 660 x - 84 = 0
