8 x^{2} - 30 x - 27 = 0

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

Decimal Notation

x = 4.5, x = - 0.75

Solution steps

8 x^{2} - 30 x - 27 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 8 ( - 27 )}{2 \cdot 8}

(- 30)^{2} - 4 \cdot 8 (- 27) = 42

x_{1, 2} = \frac{- ( - 30 ) \pm 42}{2 \cdot 8}

Separate the solutions

x_{1} = \frac{- ( - 30 ) + 42}{2 \cdot 8}, x_{2} = \frac{- ( - 30 ) - 42}{2 \cdot 8}

x = \frac{- ( - 30 ) + 42}{2 \cdot 8} : \frac{9}{2}

x = \frac{- ( - 30 ) - 42}{2 \cdot 8} : - \frac{3}{4}

The solutions to the quadratic equation are:

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

- 2 + \frac{p}{5} \leq 10

\frac{x}{9} + x = \frac{7}{18}

2^{n + 1} + 2^{n}

\frac{x ^{2} - 3 x - 4}{x ^{2} - 4 x - 5} < 0

6 x^{2} - 27 x - 54
