4 x^{2} - 18 = 0

x = \frac{3}{2}, x = - \frac{3}{2}

Decimal Notation

x = 2.12132 \dots, x = - 2.12132 \dots

Solution steps

4 x^{2} - 18 = 0

Move

18

to the right side

4 x^{2} = 18

Divide both sides by

4

x^{2} = \frac{9}{2}

For

x^{2} = f (a)

the solutions are

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

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

\frac{9}{2} = \frac{3}{2}

- \frac{9}{2} = - \frac{3}{2}

x = \frac{3}{2}, x = - \frac{3}{2}

x + 8 = 3 x

5 x^{5} - 10 x^{4} - 40 x^{3}

z^{2} - 7 z + 12

- 30 p^{4} + 39 p^{2} q^{3} + 39 p^{2} q^{2}

2 x + 24 + x - 30 = x + 13 + x - 15
