7 x^{2} - 13 x - 2 = 0

x = 2, x = - \frac{1}{7}

Decimal Notation

x = 2, x = - 0.14285 \dots

Solution steps

7 x^{2} - 13 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 7 ( - 2 )}{2 \cdot 7}

(- 13)^{2} - 4 \cdot 7 (- 2) = 15

x_{1, 2} = \frac{- ( - 13 ) \pm 15}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- ( - 13 ) + 15}{2 \cdot 7}, x_{2} = \frac{- ( - 13 ) - 15}{2 \cdot 7}

x = \frac{- ( - 13 ) + 15}{2 \cdot 7} : 2

x = \frac{- ( - 13 ) - 15}{2 \cdot 7} : - \frac{1}{7}

The solutions to the quadratic equation are:

x = 2, x = - \frac{1}{7}
