10890 = 9000 (1 + r)^{2}

r = \frac{1}{10}, r = - \frac{21}{10}

Decimal Notation

r = 0.1, r = - 2.1

Solution steps

10890 = 9000 (1 + r)^{2}

Switch sides

9000 (1 + r)^{2} = 10890

Divide both sides by

9000

(1 + r)^{2} = \frac{121}{100}

For

(g (x))^{2} = f (a)

the solutions are

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

Solve

1 + r = \frac{121}{100} : r = \frac{1}{10}

Solve

1 + r = - \frac{121}{100} : r = - \frac{21}{10}

The solutions to the quadratic equation are:

r = \frac{1}{10}, r = - \frac{21}{10}

\frac{6 x ^{10} y ^{4}}{3 x ^{8} y ^{7}}

x^{2} - 5 x - 84

\frac{x}{2} + 3 < 12

(- \frac{2}{5})^{- 1}

1 \leq - 7 - (a + 2) \leq 5
