\frac{9}{16} - \frac{x ^{2}}{81} = 0

x = \frac{27}{4}, x = - \frac{27}{4}

Decimal Notation

x = 6.75, x = - 6.75

Solution steps

\frac{9}{16} - \frac{x ^{2}}{81} = 0

Move

\frac{9}{16}

to the right side

- \frac{x ^{2}}{81} = - \frac{9}{16}

Multiply both sides by

81

- x^{2} = - \frac{729}{16}

Divide both sides by

- 1

x^{2} = \frac{729}{16}

For

x^{2} = f (a)

the solutions are

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

x = \frac{729}{16}, x = - \frac{729}{16}

\frac{729}{16} = \frac{27}{4}

- \frac{729}{16} = - \frac{27}{4}

x = \frac{27}{4}, x = - \frac{27}{4}

0.4 x^{2} + 1.5 x - 1.3 = 0

s^{2} + s + 5

(- \frac{11}{4})^{2} + y^{2} = 1

x^{2} + 9 x + 18 = 0

x^{2} - 7.2 x + 12.8 = 0
