0 = 5 x^{2} - 16

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

Decimal Notation

x = 1.78885 \dots, x = - 1.78885 \dots

Solution steps

0 = 5 x^{2} - 16

Switch sides

5 x^{2} - 16 = 0

Move

16

to the right side

5 x^{2} = 16

Divide both sides by

5

x^{2} = \frac{16}{5}

For

x^{2} = f (a)

the solutions are

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

x = \frac{16}{5}, x = - \frac{16}{5}

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

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

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

s^{2} + 4 s + 7 = 0

2 x^{2} - 5 x = - 1

2 x (x - \frac{7}{2}) = 49

r, r^{2} + 1 = 0

6 x^{2} + 24 x - 30 = 0
