8 x^{2} - 14 x - 15 = 0

x = \frac{5}{2}, x = - \frac{3}{4}

Decimal Notation

x = 2.5, x = - 0.75

Solution steps

8 x^{2} - 14 x - 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 14 ) \pm ( - 14 ) ^{2} - 4 \cdot 8 ( - 15 )}{2 \cdot 8}

(- 14)^{2} - 4 \cdot 8 (- 15) = 26

x_{1, 2} = \frac{- ( - 14 ) \pm 26}{2 \cdot 8}

Separate the solutions

x_{1} = \frac{- ( - 14 ) + 26}{2 \cdot 8}, x_{2} = \frac{- ( - 14 ) - 26}{2 \cdot 8}

x = \frac{- ( - 14 ) + 26}{2 \cdot 8} : \frac{5}{2}

x = \frac{- ( - 14 ) - 26}{2 \cdot 8} : - \frac{3}{4}

The solutions to the quadratic equation are:

x = \frac{5}{2}, x = - \frac{3}{4}

5 - x > 0

\frac{1}{\frac{1}{x} + \frac{1}{y}}

x^{3} + x - 2

\frac{1}{3} x + \frac{1}{4} = \frac{1}{2}

(\frac{t}{2})^{3}
