84 x^{2} - 8 = 0

x = \frac{2}{21}, x = - \frac{2}{21}

Decimal

x = 0.30860 \dots, x = - 0.30860 \dots

Solution steps

84 x^{2} - 8 = 0

Move

8

to the right side

84 x^{2} = 8

Divide both sides by

84

x^{2} = \frac{2}{21}

For

x^{2} = f (a)

the solutions are

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

x = \frac{2}{21}, x = - \frac{2}{21}

p^{2} - 16 p + 39 = 0
