x^{2} - \frac{81}{4} = 0

x = \frac{9}{2}, x = - \frac{9}{2}

Decimal Notation

x = 4.5, x = - 4.5

Solution steps

x^{2} - \frac{81}{4} = 0

Move

\frac{81}{4}

to the right side

x^{2} = \frac{81}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{81}{4}, x = - \frac{81}{4}

\frac{81}{4} = \frac{9}{2}

- \frac{81}{4} = - \frac{9}{2}

x = \frac{9}{2}, x = - \frac{9}{2}

t, - \frac{1}{2} \cdot g \cdot t^{2} + v \cdot t = 0

x^{2} - 12 x + 36 = x

2 x^{2} - 12 x + 14

(2 x)^{2} = 36

x^{2} + 2
