15 x^{2} - 2 x - 1 = 0

x = \frac{1}{3}, x = - \frac{1}{5}

Decimal Notation

x = 0.33333 \dots, x = - 0.2

Solution steps

15 x^{2} - 2 x - 1 = 0

Solve with the quadratic formula

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

(- 2)^{2} - 4 \cdot 15 (- 1) = 8

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

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 8}{2 \cdot 15}, x_{2} = \frac{- ( - 2 ) - 8}{2 \cdot 15}

x = \frac{- ( - 2 ) + 8}{2 \cdot 15} : \frac{1}{3}

x = \frac{- ( - 2 ) - 8}{2 \cdot 15} : - \frac{1}{5}

The solutions to the quadratic equation are:

x = \frac{1}{3}, x = - \frac{1}{5}

\frac{- e ^{6}}{e ^{3} - e ^{6}}

x^{2} y + x^{2} z
