20 x^{2} - 45 = 0

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

Decimal Notation

x = 1.5, x = - 1.5

Solution steps

20 x^{2} - 45 = 0

Move

45

to the right side

20 x^{2} = 45

Divide both sides by

20

x^{2} = \frac{9}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{9}{4}, x = - \frac{9}{4}

\frac{9}{4} = \frac{3}{2}

- \frac{9}{4} = - \frac{3}{2}

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

5 x^{2} + 6 x + 5 = 2 (2 x^{2} + 10) - 4 x

0 = 19.23 x + 3.25 x^{2}

- \frac{\frac{8}{7}}{( - \frac{10}{9} )}

x^{2} < x + 6

m^{2} - 6 m + 8 > 0
