3 x^{2} - 11 x - 20 = 0

x = 5, x = - \frac{4}{3}

Decimal Notation

x = 5, x = - 1.33333 \dots

Solution steps

3 x^{2} - 11 x - 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 11 ) \pm ( - 11 ) ^{2} - 4 \cdot 3 ( - 20 )}{2 \cdot 3}

(- 11)^{2} - 4 \cdot 3 (- 20) = 19

x_{1, 2} = \frac{- ( - 11 ) \pm 19}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 11 ) + 19}{2 \cdot 3}, x_{2} = \frac{- ( - 11 ) - 19}{2 \cdot 3}

x = \frac{- ( - 11 ) + 19}{2 \cdot 3} : 5

x = \frac{- ( - 11 ) - 19}{2 \cdot 3} : - \frac{4}{3}

The solutions to the quadratic equation are:

x = 5, x = - \frac{4}{3}

\frac{x ^{2} - 4}{x ^{2} + 36} \leq 0

- \frac{6}{5} t = 9

- \frac{10 ( - 2 ) + 2}{( 5 ( - 2 ) ^{2} + 2 ( - 2 ) ) ^{2}}

x^{5}

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